Thank you for the Laurel/Yanny example. For years I've tried to understand how, on numerous occasions, when I've told someone my last name, "Nord", they have responded back, asking "Miller?"
Speaking of the Levitin effect, as a musician, I hear melodies in my head when I experience inspiration. But I don't hear them tuned to a reference pitch of 440 Hz; I hear them tuned to a reference pitch of 430 Hz (classical pitch). Until I figured this out, it used to aggravate the fuck out of me when I tried rendering the melodies on my bass, because the notes always seemed to be somewhere between two frets. Nothing sounded right when I was tuned to 440, and I was always having to make a judgement call about where to place the notes. I believe that this is my internal reference because as a child, I listened to classical recordings from a series that had been recorded tuned to classical pitch. Because of my young age and because of the intensity of the emotional experience, I was imprinted by these tones rather than by 440-based tones. So I have some degree of perfect pitch, but it's for equal temperament tuned to 430 Hz rather than 440 Hz. I have good relative pitch though, so although 440 tuning sounds sharp to me, it still sounds right in terms of intervals.
i percieved something that was if you listened a music very low, you will miss the parts and almost missunderstand the music, but once you know the music, have already listened it loud or know every single detail, once you identify the music it gains quality and you can really perceave the low music with a high quality one
As someone who loves hip-hop and sampling, the whole speech to song thing is interesting in that vocal samples can play a huge part in the creation of a beat and do play a huge part in turntable scratching.
For the talking piano one, I converted a very familiar song into midi and could perfectly hear the voices, even to the point to were I could easily sing along. It seems that the more familiar you are with a song, the more your brain can fill in and differentiate. Like I said, despite all the messy piano noise going on I could still easily hear all the different parts including the vocals.
The "talking piano" is how modern communication systems work. Many decades ago, I worked on things called vocoders. These "measure" the frequencies in input speech and then either store or transmit a description of those frequencies and their amplitudes. To reconstruct the speech, sine waves at the appropriate frequencies are recreated and mixed together. The advantage of this is that it requires much less bandwidth than would be needed to store or transmit the speech waveform directly. If done properly, the reconstructed speech is almost indistinguishable from the original. Modern mobile phones use a digital version of this process.
The precedence effect and Clifton effect seems to explain why that when two or more people say the same thing at once, it's impossible to understand them because you can't focus one one voice. This has happened before to me when I was in high school. I had been confused about something and then the whole class at once said the same thing and I had no idea what they had just said, so I yelled at them (bc they're very loud) to only let one person reply to my question.
Music producer here - I believe the Kubovy/Cutting/Mcguire effect is related to the Haas effect. The minute delay in frequency perception between both ears creates a sensation of the sound being in a different space on the stereo spectrum, which causes it to stand out from the rest of the sound. Even though there is no change in volume, we tend to perceive it as clearer. This is actually utilized intentionally within stereo separation software so we are able to create clarity of sound without infinitely increasing volume of a sound, which is critical in mixing
Right! I have occasional Diplacusis, thanks for naming that for me. Thankfully i haven't had it happen now for a few years. The other effect was to add a metallic or robot quality to higher pitched sounds (female voices for instance) and it was that rather then the pitch difference, that heralded an "attack". At first I was dismayed, being a musician, but its not occurred now for 3-4 years at least, so fingers crossed!
8:51 I'm a psych student obsessed with music and i've found that for me it's impossible to sing microtonally or "out of tune". I think our brains subconsciously remembers the characteristics of music that is the reason it sound good. So even without perfect pitch it's able to replicate the frequencies of notes perfectly because that's what sounds good to it, or more professionally what music is natural to our brain. I've also noticed it's easier to create melodies vocally than on instruments. I think this effect should be studied more considering how our brains and music are link, like how speech follows rhythmic patterns (PB&J sounds natural buy J&PB doesn't) that sound natural to our brains but melodically.
really cool to see the speech to song illusion! I used to watch the tv show Fawlty Towers a LOT when I was a kid, and I have most of the lines memorised. Interestingly enough, for years I had noticed that I remembered the specific rhythm of how the lines were spoken and recalled them almost as though they were song lyrics
5:10 Mute the audio and watch it again. Then watch it again with the audio cues. Really quite interesting that audio cues can influence our vision in that way even when you know the dot isn't flashing with the beeps you still see it flash. Brains are weird.
In the Mysterious Melody segment, I was never able to just "hear" the song, but there was just enough context clue with the rhythm and the couple of notes that landed on a common octave to figure out what song it was before it was revealed the first time. Not sure that this enters anything into the equation for research into the illusion but like.. yeah
I was wondering if you would address yanny/laurel and I'm glad you did. At the time, I was able to focus my ears to hear either one at will. When you know what the illusion is supposed to be, you can do mental gymnastics to force yourself to hear either one. Sound is so fascinating!
the speech to song illusion makes me think about key, and how natural voice tones might seem like a chord progression when going through parts of a sentence, combine that with a tempo to put these progressions along and you can't help but hear music in people's voices as they speak. I'm no major in music theory, but that's my take on the illusion.
When you started playing the beeps the second time with the flashes, the first time I saw the second one of those flashes, for some reason I saw it way off-centre near the top-left corner.
I was able to get the last one to work with my phones earbuds. I’m in a quiet room and with the volume turned up a bit I removed them and held them out in front of me but a little farther apart than my bead, evenly spaced from me. When held in the right space I could hear the illusion.
Hey I just want to comment one speech melody, which is the first illusion. Both Steve Reich, and Jacob TV use this to great effect in several of there pieces. I think it's worth a greater discourse in the musical community. I've a couple of pieces for instrument and tape that use it, and I think it's something with a lot of multifaceted potential.
to really appreciate the franssen effect listen again on headphones. the sound is not slowly transitioning to the other speaker as you'd expect based on in the video, but almost instantaneously flips to the other side.
I listened to it with headphones the first time and sounded like it started from left then went behind my left ear around the back of my head to my right ear hole then the beeps at the end was behind my right ear...did I do it right?
I was very interested in the Levitin effect! 😃 It reminds me (back in the day) of when I was listening to a favorite song on a friend's tape recorder, and I told him his tape player was faster than mine because the music sounded too high. I don' have perfect pitch either. Anyway, he did not believe me, so I went home and grabbed my tape player. We timed how long the song lasted on my tape player: 3:19 and on his? 3:17. If my calculation is correct, that equates to a difference of about 17% of a semi-tone!
The speech to song example in this video didn't really get me, but there was a video I saw where the quote was "sometimes behaves so strangely" and I still hear it as a tune rather than a sentence
Yanny/Laurel: I could only hear Yanny when I was first introduced to it, then after watching an explanation of it that played the original unmodified clip, I can only hear Laurel. Even after not hearing or thinking about it for a couple years, coming back to it I only hear Laurel in the ambiguous clip. Kubovy/Cutting/McGuire effect: I'm guessing the melodic notes in either channel are exact waveform inverts of each other. That way when rendered into a single channel they cancel out perfectly and aren't even in the recording, not merely not heard. Then when played in opposite ears we hear it because differing phases in different ears is common and part of how we locate the source of a sound. Similarly if you take a song and invert one channel of it in Audacity (or if you have earphones with 2-pin connectors, you can just flip the connector on one side to reverse its polarity), you still hear everything, but it kind of wrecks the stereo effect and makes sounds hard to place. Levitin effect: I swear, for me when I dream music it's like a straight recording of the (processed) sensory input, and I don't dream music if it isn't fresh enough in my head to play back. For instance, after binge watching an anime, that night I dreamed the opening theme from it, with both correct pitch and correct lyrics even though I don't have perfect pitch and don't know Japanese. Or at least when I listened to the song the next day the music and lyrics perfectly matched my memory of it in the dream, so I suppose some memory wibbly-wobbliness is also possible. Similarly, just the first few seconds of a track I've listened to thousands of times over the years is all it takes for me to tell whether something is off in the frequency response of a sound system, even if songs I don't know as well sound perfectly normal.
So for the Levitin Effect (9:00), if I listen to a concert piece and play the timpani in it, would I remember the accurate pitch for the piece (assuming that is what I practice to) or would I hear the overtones of the timpani I am playing? Interesting series for a musician to watch.
If the effect is happening, my understanding is that you'd hear whatever you were paying attention to, and in accurate pitch. I.e. either, depending on your focus, but they'd both be 'correct'.
Speech to song: since the pitches encountered in ordinary speech generally don't map to any familiar scale of notes, the initial perception is correct: speech. However, when the exact sample is repeated, because it's an exact repetition, the rhythm and pitches all remain the same. By contrast, when you actually repeatedly say the phrase, you vary the rhythm and pitch contour without even really noticing. So, an exact repetition of pitch and rhythm is a strong clue that what you're hearing is music, and it overrides the initial perception as speech.
You can make a piano repeat any non-frequency-changing voice sound, e.g., eh, ah, and ee. To do this, keep the sustain pedal down and say the vowel loudly onto the strings. The sustain pedal still being down, you should hear the piano saying that sound though somewhat quieter. Depending on the piano, you will have to expose the strings to your voice to get this to happen well. What is happening is that the strings will resonate like a large spectrum analyzer to the frequencies in your sound.
On the Kubovy/Cutting/McGuire effect, I heard a melody all three times. The one in the middle segment did seem different than the others. The first and last seemed pretty similar. The third was definitely louder than the others. I was listening to this on a iPhone, not a computer with headphones, so not sure if that makes a difference.
Darn, that's my favorite one. :-) Are you wearing headphones? Even if you are, it's possible that audio routing in your system might be cross-talking between channels and ruining the effect. Maybe try on a friend's computer with different headphones.
The 225hz tone was a simulation of what the Huggins pitch would sound like. I can just barely hear it, it helps to listen to the simulated tone to kind of get your ear ready for what it will hear. He is right though if theres much background noise around you won't be able to hear it.
Re; the Kubovy/Cutting/McGuire effect; Dr. Kubovy and Dr. Diana Deutsch handed out headphones to 3000 attendees at an AES convention. The tones played "are you sleeping, brother John" whereas the one here was just an ascending scale. It was a sensation at the event. I can't find a free phase modulator online .....I was curious what it would sound like binaurally to have a mono pink noise fed to both left and right but in one channel only, employ a phase modulator driven by a voice. Maybe I would need a "delay modulator' instead, but it might reproduce a voice only when listening to both channels , hearing just straight pink noise with either alone.
For the sound-induced flash illusion I only ever saw the dot flash once, I had to really try to see it flash twice, could that be because some people are more "visual" than others? I understand and remember things better in images, I struggle sometimes with speech and listening or remembering what I've heard (all of this especially more so when I was younger though) Thoughts on this? I just found this really interesting bc this was like the one illusion I didn't get "trapped" in as soon as a visual element was put into it so I might be flexing a bit lol
Yeah I don't know... I expect there is a fair bit of variation between folks on this. It's also hard to faithfully reproduce that illusion over youtube because audio/video sync is kind of a mess from computer to computer. So I wouldn't necessarily draw too much from it. :-)
Is there a trick to this, like hearing with headphones/speakers? I guess I may mistake the first version as "Yanny" if Im drunk enough. The second one is clearly "tweaked", as in: someone is saying "Yanny" in a microphone :D
The McGuire Effect is the audio version of the famous Magic Eye images, where a seemingly messed up image needs to be defocused to perceive an afterimage. Instead the same noises are consolidated and put out of phase.
Awesome video series. Question about an illusion that I hear. Certain instruments, like brass, trumpet, if the volume is high, the I hear distorted high harmonics, while the organ is not distorted at all. Both instruments are live, I.e. not recording, and are played at about the same intensity. What is this illusion? Thanks
Hmmm... My best guess is that since the trumpet has more upper harmonics than an organ (usually) those upper harmonics are distorting in your ear. I.e. it would be a physical distortion in your ear, as opposed to a psychoacoustic phenomenon. You specified live rather than recorded: sometimes we unconsciously tolerate louder volumes with live music than recorded (though the opposite can be true, especially with headphones). It's possible too that it is harmonics above the limit of hearing that are creating intermodulation products down into the audible range (which might explain why recorded music doesn't do it) but I'm not 100% sure how plausible that really is. I've heard strange distortion products in the presence of a crowd of screaming/howling people (celebrating, don't worry :-) )... Sounds similar to what you describe.
I "had" diplacusis once. I vividly remember that I was suuper tired, exhausted, and completely lost it when I realized that a melody I knew sounded completely out of tune of sorts 😂 Luckily a good night sleep made the difference and been cured since^^
Believe it or not. you DO have perfect pitch! The ability to remember (which is what you're actually doing) pitch accurately is all perfect pitch actually is. I suspect you just haven't developed it . Think of a song. Find out what KEY the song is in. Then when asked for that particular note, play the song in your head. Sing the key note. Done. Of course, you'd have to do this for twelve different songs one in each key, but I've found that 3 or 4 will suffice. You can pick your fave song and DO RE MI in your head 'till you've found the one that matches.I am a guitar player and have been doing this all my life, Two or three strings memorized is all you really need, The rest can all be worked out relative on your instrument or in your head! I can't think of twelve songs, one in each key,some of the sharps/flats are seldom used in a POP idiom. Here are my fave references: Heart and soul on the white piano keys "C" Doobie brothers "China grove" " E" Beatles "Here comes the sun" "A" Beatles "Revolution" A sharp/B flat. Find a few of your own and good luck! Love this series man. Some very good work here, very well researched and presented. You get two gold stars and a puppy sticker! BTW, Your little trick with the "Two mics" didn't fool me either, Not boasting.' I had attributed the lack of a difference to a lack of headphones, and listening to the playback on this notebook with its tiny speakers the size of a Quarter. I would argue that transposing the notes of a melody up or down an octave, result in a DIFFERENT MELODY, melody being DEFINED by the sequences of the pitches. Different pitches=different melody.(duration is important too of course!)Cheers nd thumbs way up!
not true. if you remember a song well enough from hearing/singing/playing it often enough, you can remember the pitch of its note, even if you don’t have perfect pitch. I watched a video on it today. let me link it
here th-cam.com/video/QRaACa1Mrd4/w-d-xo.html . the section on quasi-perfect pitch talks about it. I’m able to identify an F3 and noticed that a piano was a semitone out of tune, simply because I used to sing a song which started on an F3. I don’t have perfect pitch though
If you didn't interpret the Franssen effect correctly, don't feel bad. It's very subtle and even hard to get even in headphones. What I heard was a blip on one side and then the tone just stuck in one ear, and then the beeps. I plugged in to my soundboard with indication lights for stereo and volume and I saw this was visually correct. I was expecting the fade to last longer and was confused at first. It took at least 3 times listening to it to understand what was happening.
The KCM effect sounds so awesome to me. Like I kind of want to listen to it for a long time. I kind of want to play with it and see if I can make an actually melody out of it, maybe by altering the timing and pitch of that little staticy beat.
@@CaseyConnor I listened to it several times, and I think part of it is similar to an earlier effect where it is easier to pick a sound out from a crowd. When the click happens, it blocks the sound, and when it comes back we notice the difference between the two again, so we assume the slightly higher pitched note is the one we were following. It's not a perfect explanation, because if that were it why wouldn't we hear it going back down the scale, but I still feel they are linked somehow.
Yeah I agree -- it's as if the phase shift draws our auditory system's attention, and that attention allows us to perceive that art of the spectrum as a louder note.
the talking piano is quite scary...also in my culture (ghana) we have something called the talking drum (atumpan), which is used to "talk to the audience" and mimic what the speaker said via tonation so imagine if you said "how are you doing today?" and imagine a drum mimic that tonation
The so-called talking piano effect is directly related to vocoders and using of this effect in telephony, voice data compression, electronic music etc.
9:36 This is actually not odd at all. The Major scales were popularised because of their cheerful sound, and the C is centered around people's vocal range. So it's not that they are copying music, but that music copies them.
Speech to Song illusion... the reason why hip hop is considered "music" Mystery note effect: how bassists in heavy bands think they're playing in key, when in fact, hitting random notes.
There's a similar effect to the Yanny/Laurel effect that I called the Mere/May effect. It's the same thing but if you pitch "Mere" down enough you'll hear "May" instead.
for the talking piano, if you don't know the lyrics/there are no lyrics, you can make it say whatever you want. I took Beethoven's 5th symphony and made it sing "Under the Sea" from The Little Mermaid.
@@CaseyConnor No worries. I thought it was funny and honestly intentional. If it helps, the hilarity of it made me sit through the whole ad without skipping
The Huggins Effect strikes me as being the same sound which psychics interpret as spirit talking to them when they employ their Electronic Voice Recording "technique".
So with the Franssen Effect I immediately identified the sound going left to right, but in the second example I kept hearing it to the right. Could this be the acoustics of my room or am I just fucked? Maybe handedness has an effect here too? Porque no los dos? Why do we exist?
Room acoustics could certainly matter, but i also wouldn't be surprised if there was a fair amount of variation from person to person on that one. Maybe give it a shot a different system somewhere?
The aliens in a story I was writing had an extreme version of the Levitin effect, and sounds outside of integer multiples of their village’s favored root note sounded icky and grating…part of the coming together of societies and process of integration into empires consisted of accepting an alteration of the tonal affinity, and their modern globalized world involved a single standard tone. Which would up being outside their hearing range because I gave them a narrow hearing range but wanted their music to have more bass notes, but could only use the harmonic series. But since then, I’ve been wondering why not everyone has this, since tones excite specific hearing cells in specific locations in the ear. I’m now feeling pretty sure everyone has perfect pitch and we learn to ignore it somehow
With the yanny and laurel thing, I have heard younger people tended towards yanny due to it being in the higher pitch while laurel was in the lower pitch I heard yanny when I was younger, but likely due to working in a metal parts factory where we use hammers and loud tools or because I heard a heavily biased one
This series is criminally underrated.
I agree. Deserves a much higher viewership.
.yep.

Kubovy/Cutting/McGuire effect: I'm guessing the melodic notes in either channel are exact waveform inverts of each other. That way when rendered into a single channel they cancel out perfectly and aren't even in the recording, not merely not heard. Then when played in opposite ears we hear it because differing phases in different ears is common and part of how we locate the source of a sound. Similarly if you take a song and invert one channel of it in Audacity (or if you have earphones with 2-pin connectors, you can just flip the connector on one side to reverse its polarity), you still hear everything, but it kind of wrecks the stereo effect and makes sounds hard to place.
Levitin effect: I swear, for me when I dream music it's like a straight recording of the (processed) sensory input, and I don't dream music if it isn't fresh enough in my head to play back. For instance, after binge watching an anime, that night I dreamed the opening theme from it, with both correct pitch and correct lyrics even though I don't have perfect pitch and don't know Japanese. Or at least when I listened to the song the next day the music and lyrics perfectly matched my memory of it in the dream, so I suppose some memory wibbly-wobbliness is also possible. Similarly, just the first few seconds of a track I've listened to thousands of times over the years is all it takes for me to tell whether something is off in the frequency response of a sound system, even if songs I don't know as well sound perfectly normal.
So for the Levitin Effect (9:00), if I listen to a concert piece and play the timpani in it, would I remember the accurate pitch for the piece (assuming that is what I practice to) or would I hear the overtones of the timpani I am playing? Interesting series for a musician to watch.
If the effect is happening, my understanding is that you'd hear whatever you were paying attention to, and in accurate pitch. I.e. either, depending on your focus, but they'd both be 'correct'.
@@CaseyConnor That's really cool. Thanks for answering my messy question. You earned a new sub!
Speech to song: since the pitches encountered in ordinary speech generally don't map to any familiar scale of notes, the initial perception is correct: speech. However, when the exact sample is repeated, because it's an exact repetition, the rhythm and pitches all remain the same. By contrast, when you actually repeatedly say the phrase, you vary the rhythm and pitch contour without even really noticing. So, an exact repetition of pitch and rhythm is a strong clue that what you're hearing is music, and it overrides the initial perception as speech.
You can make a piano repeat any non-frequency-changing voice sound, e.g., eh, ah, and ee. To do this, keep the sustain pedal down and say the vowel loudly onto the strings. The sustain pedal still being down, you should hear the piano saying that sound though somewhat quieter. Depending on the piano, you will have to expose the strings to your voice to get this to happen well. What is happening is that the strings will resonate like a large spectrum analyzer to the frequencies in your sound.
well done! this is so cool for my mind! mind blown
8:19 i heard all 8 notes of eb or d major scale.
On the Kubovy/Cutting/McGuire effect, I heard a melody all three times. The one in the middle segment did seem different than the others. The first and last seemed pretty similar. The third was definitely louder than the others. I was listening to this on a iPhone, not a computer with headphones, so not sure if that makes a difference.
I wonder if the ambient sound from rooms etc can be moved from side to side like with the swaying of a ship?
Such a good channel
8:49 definitely getting nothing out of this McGuire effect
Darn, that's my favorite one. :-) Are you wearing headphones? Even if you are, it's possible that audio routing in your system might be cross-talking between channels and ruining the effect. Maybe try on a friend's computer with different headphones.
The only pitch I heard in the Huggins pitch segment was the 2kHz peak. What was the 225Hz tone supposed to do?
I heard a click sound right before each phase shift happened, and then another after a moment.
The 225hz tone was a simulation of what the Huggins pitch would sound like. I can just barely hear it, it helps to listen to the simulated tone to kind of get your ear ready for what it will hear. He is right though if theres much background noise around you won't be able to hear it.
I couldn’t hear anything first time either. I replayed it and the visual cue on the video helped, it’s quite faint.
"It's a fun game you and your subconscious brain can play together"
Thanks so much for posting these
wow, Kubovy/Cutting/McGuire effect sounds like an EQ emphasizing overtones one by one, higher and higher
Yeah i thought that one was pretty neat!
Re; the Kubovy/Cutting/McGuire effect; Dr. Kubovy and Dr. Diana Deutsch handed out headphones to 3000 attendees at an AES convention. The tones played "are you sleeping, brother John" whereas the one here was just an ascending scale. It was a sensation at the event.
I can't find a free phase modulator online .....I was curious what it would sound like binaurally to have a mono pink noise fed to both left and right but in one channel only, employ a phase modulator driven by a voice. Maybe I would need a "delay modulator' instead, but it might reproduce a voice only when listening to both channels , hearing just straight pink noise with either alone.
I like that idea... If i get some time some day I'll code something up and see what happens...
For the sound-induced flash illusion I only ever saw the dot flash once, I had to really try to see it flash twice, could that be because some people are more "visual" than others? I understand and remember things better in images, I struggle sometimes with speech and listening or remembering what I've heard (all of this especially more so when I was younger though)
Thoughts on this? I just found this really interesting bc this was like the one illusion I didn't get "trapped" in as soon as a visual element was put into it so I might be flexing a bit lol
Yeah I don't know... I expect there is a fair bit of variation between folks on this. It's also hard to faithfully reproduce that illusion over youtube because audio/video sync is kind of a mess from computer to computer. So I wouldn't necessarily draw too much from it. :-)
For the Franssen effect, I heard the fade from left to right. Does that mean anything?
I literally never hear YANNY... even if its "been tweaked to sound like Yanny"
I literally ONLY heard Yanny...
@@timehlers9651 I was honesty very tempted to reply "and you'd be wrong :)" lmao
Is there a trick to this, like hearing with headphones/speakers?
I guess I may mistake the first version as "Yanny" if Im drunk enough. The second one is clearly "tweaked", as in: someone is saying "Yanny" in a microphone :D
I could hear Yanny by holding my headphones away from my head
6:38, isn't this similar to how a vocoder works
Yes indeed.
The McGuire Effect is the audio version of the famous Magic Eye images, where a seemingly messed up image needs to be defocused to perceive an afterimage. Instead the same noises are consolidated and put out of phase.
The Franssen effect didn't really work on me, I heard a loud beginning to the sound on one side and then it continued on the other?
2:02 - Actually, it took me a while to recognize the original version at that tempo.
2:42 - "I hear... Covfefe." D.J.T., 2018
Awesome video series. Question about an illusion that I hear. Certain instruments, like brass, trumpet, if the volume is high, the I hear distorted high harmonics, while the organ is not distorted at all. Both instruments are live, I.e. not recording, and are played at about the same intensity. What is this illusion? Thanks
Hmmm... My best guess is that since the trumpet has more upper harmonics than an organ (usually) those upper harmonics are distorting in your ear. I.e. it would be a physical distortion in your ear, as opposed to a psychoacoustic phenomenon. You specified live rather than recorded: sometimes we unconsciously tolerate louder volumes with live music than recorded (though the opposite can be true, especially with headphones). It's possible too that it is harmonics above the limit of hearing that are creating intermodulation products down into the audible range (which might explain why recorded music doesn't do it) but I'm not 100% sure how plausible that really is. I've heard strange distortion products in the presence of a crowd of screaming/howling people (celebrating, don't worry :-) )... Sounds similar to what you describe.
I "had" diplacusis once. I vividly remember that I was suuper tired, exhausted, and completely lost it when I realized that a melody I knew sounded completely out of tune of sorts 😂
Luckily a good night sleep made the difference and been cured since^^
for dipalacusis I was so worried you where gonna say it was the same frequency and I got duped by confirmation bias
Talking piano is something I...I don't even know how to say. This drives me crazy!!!
Did not understand Huggins pitch, pretty sure noise is always equally stereo? Only heard clicks in that bit
Believe it or not. you DO have perfect pitch! The ability to remember (which is what you're actually doing) pitch accurately is all perfect pitch actually is. I suspect you just haven't developed it . Think of a song. Find out what KEY the song is in. Then when asked for that particular note, play the song in your head. Sing the key note. Done. Of course, you'd have to do this for twelve different songs one in each key, but I've found that 3 or 4 will suffice. You can pick your fave song and DO RE MI in your head 'till you've found the one that matches.I am a guitar player and have been doing this all my life, Two or three strings memorized is all you really need, The rest can all be worked out relative on your instrument or in your head! I can't think of twelve songs, one in each key,some of the sharps/flats are seldom used in a POP idiom. Here are my fave references: Heart and soul on the white piano keys "C"
Doobie brothers "China grove" " E" Beatles "Here comes the sun" "A" Beatles "Revolution" A sharp/B flat. Find a few of your own and good luck! Love this series man. Some very good work here, very well researched and presented. You get two gold stars and a puppy sticker!
BTW, Your little trick with the "Two mics" didn't fool me either, Not boasting.' I had attributed the lack of a difference to a lack of headphones, and listening to the playback on this notebook with its tiny speakers the size of a Quarter.
I would argue that transposing the notes of a melody up or down an octave, result in a DIFFERENT MELODY, melody being DEFINED by the sequences of the pitches. Different pitches=different melody.(duration is important too of course!)Cheers nd thumbs way up!
not true. if you remember a song well enough from hearing/singing/playing it often enough, you can remember the pitch of its note, even if you don’t have perfect pitch. I watched a video on it today. let me link it
here th-cam.com/video/QRaACa1Mrd4/w-d-xo.html . the section on quasi-perfect pitch talks about it. I’m able to identify an F3 and noticed that a piano was a semitone out of tune, simply because I used to sing a song which started on an F3. I don’t have perfect pitch though
@@icanseeyou9820 Thanx. show us the link!
@@bobbyfeatherstone2834 I sent the link in my second comment :)
Talking Piano - Steve! Steve! We could be soooo happy, Steve!
If you didn't interpret the Franssen effect correctly, don't feel bad. It's very subtle and even hard to get even in headphones.
What I heard was a blip on one side and then the tone just stuck in one ear, and then the beeps. I plugged in to my soundboard with indication lights for stereo and volume and I saw this was visually correct.
I was expecting the fade to last longer and was confused at first. It took at least 3 times listening to it to understand what was happening.
With Huggins pitch, I just hear a slight tap kinda noise that you'd hear when starting a record player when it started and stopped
The KCM effect sounds so awesome to me. Like I kind of want to listen to it for a long time. I kind of want to play with it and see if I can make an actually melody out of it, maybe by altering the timing and pitch of that little staticy beat.
That's my favorite one from the whole series, I think... in part because it's such a weird effect with no real explanation.
@@CaseyConnor I listened to it several times, and I think part of it is similar to an earlier effect where it is easier to pick a sound out from a crowd. When the click happens, it blocks the sound, and when it comes back we notice the difference between the two again, so we assume the slightly higher pitched note is the one we were following. It's not a perfect explanation, because if that were it why wouldn't we hear it going back down the scale, but I still feel they are linked somehow.
Yeah I agree -- it's as if the phase shift draws our auditory system's attention, and that attention allows us to perceive that art of the spectrum as a louder note.
the talking piano is quite scary...also in my culture (ghana) we have something called the talking drum (atumpan), which is used to "talk to the audience" and mimic what the speaker said via tonation so imagine if you said "how are you doing today?" and imagine a drum mimic that tonation
for the "mysterious melody" effect, i recognized the music as minuet in g major, since i actually play piano
The so-called talking piano effect is directly related to vocoders and using of this effect in telephony, voice data compression, electronic music etc.
For Yanny/Laurel, I've always been able to choose which one I hear and can switch halfway through the name
connor at 4:39 : WATCH CLOSELY!!
youtube at 4:39: *plays me a commercial*
In the kubovey No melody but the last part applies pressure in the right ear
9:36 This is actually not odd at all. The Major scales were popularised because of their cheerful sound, and the C is centered around people's vocal range. So it's not that they are copying music, but that music copies them.
I want a full version of givin enough repetitions of this section you may start to hear a melody coming through
Speech to Song illusion... the reason why hip hop is considered "music"
Mystery note effect: how bassists in heavy bands think they're playing in key, when in fact, hitting random notes.
5:08 wth yes, i re watched it without sound and 1 flash only :o
There's a similar effect to the Yanny/Laurel effect that I called the Mere/May effect. It's the same thing but if you pitch "Mere" down enough you'll hear "May" instead.
Thanks, I'll check that out.
for the talking piano, if you don't know the lyrics/there are no lyrics, you can make it say whatever you want. I took Beethoven's 5th symphony and made it sing "Under the Sea" from The Little Mermaid.
Speech to Song Illusion is just how Bill Wurtz does his videos
"watch the screen and listen"....ad break lol
D'oh, sorry, I'll work on fixing that...
@@CaseyConnor No worries. I thought it was funny and honestly intentional. If it helps, the hilarity of it made me sit through the whole ad without skipping
I'm waiting for the flash! But all I see is John Cena driving..with a trunk full of MTN Dew. Dafuq?
I got Nigel Farage. Oh dear, I wish he was just an illusion.
Nah don't fix it. It's funnier that way!
2:30 : it was like 45% better but hard to very fully recognize it.
is there a full version of "given enough repetitions of this section you may start to hear a melody coming through"
Nope. :-)
@@CaseyConnor Reality is often dissapointing
The Huggins Effect strikes me as being the same sound which psychics interpret as spirit talking to them when they employ their Electronic Voice Recording "technique".
funny how in the speech to sound segment i heard a completely different melody to the one you added in.
So with the Franssen Effect I immediately identified the sound going left to right, but in the second example I kept hearing it to the right. Could this be the acoustics of my room or am I just fucked? Maybe handedness has an effect here too? Porque no los dos? Why do we exist?
Room acoustics could certainly matter, but i also wouldn't be surprised if there was a fair amount of variation from person to person on that one. Maybe give it a shot a different system somewhere?
The aliens in a story I was writing had an extreme version of the Levitin effect, and sounds outside of integer multiples of their village’s favored root note sounded icky and grating…part of the coming together of societies and process of integration into empires consisted of accepting an alteration of the tonal affinity, and their modern globalized world involved a single standard tone.
Which would up being outside their hearing range because I gave them a narrow hearing range but wanted their music to have more bass notes, but could only use the harmonic series.
But since then, I’ve been wondering why not everyone has this, since tones excite specific hearing cells in specific locations in the ear. I’m now feeling pretty sure everyone has perfect pitch and we learn to ignore it somehow
Damn, I love the mysterious melody effect.
The talking piano is also crazy amazing.
With the yanny and laurel thing, I have heard younger people tended towards yanny due to it being in the higher pitch while laurel was in the lower pitch
I heard yanny when I was younger, but likely due to working in a metal parts factory where we use hammers and loud tools or because I heard a heavily biased one
I heard yanny until this video, because I was never listening to the recording on headphones
