There is a misuse of a term - semitone. She says there are 7 semitones in an octave which is not correct. There are 7 notes in a scale spanning an octave. There are 12 semitones in an octave. Later, talking about the circle of fifths, she says there are 5 semitones between the C and G, which is the same mistake. There are 5 notes between them C, D, E, F, G, but there are 7 semitones between them. I suspect it's a problem of translation to English.
This gets into fractals that John Coltrane used in his tune Giant Steps. Great stuff! I went to a performing arts high school, majoring in Jazz Studies and Composition and we didn't even get this deep into theory. I wish we incorporated math like this back in Jazz Comp. Giant Steps would have made a lot more since back then.
Western Harmony is derieved from this 12-tone mathematically perfected relational Tonal System. It creates this computable gap between perfect Theory and the imperfect Reality. Harmony works out in nature, but not on a piece of paper. When an Instrument is played it induces its own Resonance System to the vibration of the strings. Overtones and Subharmonics are introduced. If a musician is "connected" there are no wrong notes anymore. Everything falls right into place, all boundaries are lost. Math, music and feeling all become one. Music is a beautiful art.
Step 1; explain that octaves are formed by a 2 to 1 ratio. Step 2. explain that "fifths' are formed by a 3 to 1 ratio (divided by 2 to stay in the same octave range). Step 3; explain that following the circle of fifths results in notes which are somewhat sharp (it's a spiral, not a circle). Step 4, explain that the tempered scale goes back to the 2 to 1 ratio with 12 equal ratio steps between octaves. = Note: During the time of Pythagoras, it was traditional for students and followers to attribute their works to their master. So, we really don't know how much Pythagoras did himself. . .
She gets in to the reason why you would tune in 5ths- to cover the entire chromatic scale with a relative pitch difference which you can also use to tune every note on the piano.... But step 5 would be to show that the 3:2 ratio is off by like 4 cents? Certainly tuning a piano using the 5ths by the top octave is off by an amount that can be heard hence the "comma". But irrational numbers exist so there is no need for the comma if we use the ear on each step or if we use a calculator using like 2^(7/12) instead of 3/2.
Giffy just start with learning the key signatures, take a basic lick or scale and run it thru all 12keys starting at C, then F, then Bb and so on clockwise around the circle of fifths. That will get you solid on understanding the circle of fifths and using it during practice. Then, when your comfortable with that, move in the patterns like shown in red on the video. Then your getting into fractals and John Coltrane Style, Yeah!!! Don't forget to practice with a METRONOME! 🎶
And there was silence (rest) in heaven for a span of half an hour. This is the opening verse of Revelation 8. I suppose to comprehend this mystical book, I believe it is through music.
If I am understanding this correctly, this all comes about from the inaccurate approximation of 2^(7/12) as 3/2. If it's actual value was used (1.4983) the 12 pointed star would close and there wouldn't be a Pythagorean comma. Right?
Yes, that would make the numbers work out (and lead to equal temperament). But a "just" perfect fifth is actually 3/2 - there are precisely three sound waves from one note for every two sound waves from the other note.
0:00-2:58 are the good parts. After this, it get complicated (the girl adds to much posh to it that it becomes boring). Isaac Newton said that simplicity is the best; Richard Feynman said that if one cannot explain something in simple terms, they don't understand it well. The girl's probably just targeting a specific audience(those who are advanced). However, if you want more views on your vid.............if you want more people to be into this stuff, don't sugarcoat it with incomprehensible complicatedness. Thumbs up for the video, though -I like it!, else I wouldn't be commenting it at all. I see potential in it to be more.
its only ma'am for clarification; there's only the 12 keys of the musical system, minor and major terms mostly denotes for chords.. or its better to said minor and major modes not keys.. thank you ❤️.
I'm in the early stages of grasping this and wanted to point out 4:58. She mentions harmonically equivalent notes "C and B#", but points to B flat... Is this the life-giving 1.7463 difference? Or just an accident on her part? I would think that it shoulddd echo the same pattern that is pointed at the bottom where D flat truly equals C#. Can anyone answer this?

Or a "double," as it is twice the frequency. The real answer is that it is the eight 'interval' of the seven-note (heptatonic) scale i.e. the major or minor diatonic scale (counting the unison as the first interval) e.g. C to E would be a major third; C to F a perfect fourth; C to B a major seventh; and C to C a "perfect eighth" which is instead called an octave.
Every time yall say Pythagorus yall are really and truly saying ancient Africa but can't openly admit it and the reason why ya twelve pointed star fails to close is because yall still don't get it.
So Pythagoras have been know all this and many more that today science finds out but when we speak about civilation they go back just 1or2 millenium but in order to find all those science thinks it would take at least 3 thousands years.we can’t go from runes like disk of phaistos to Pythagorean’s theorem in just 1000 years everything we have been told they are all lies.plato said when he was searching the geometric scructure that a sphaire is the most perfect form.
Her mistakes about semitones and that one extra flat on F major trigger me every time
Yeah I noticed that too
Yeah

Thank you so much for clarifying this!!
yep. good comment.
Is a semitone the number of sharps and flats? Between C and G? Counting f as a semitone?
THANK YOU
English is her 2nd language,,, maybe she mis spoke... but good point

At 15 I was listening to NWA with my buddies and learning how to party.
Good one
Ay bro, nwa hits there is nothing to be ashamed about.
I understand but don't really understand. My school project is about this. AHHHHHHHHHHH
This would be better titled: The Maths Behind Equal Temperement.

Dear friend, Namaste,
I am from Jodhpur city Rajasthan , INDIA
I want to know frequency of Harmonium's keys.
Excellent video! Thank you, Frida!
she’s really good playing math
The empirical truth of music is actually the infinite spiral of fifths based on noncommutative phase, as Alain Connes has corroborated.
I want so bad to understand!

details are details but certainly this video cracked some info

thank you
In the key signature diagram at 2:42 the key of F should only have one flat, shouldn't it?
Sorry, there's a mistake in your staff notation of the key of F on the Circle of Fifths, being that you have two flats, making it Bb, not F.
So by following your key signature for F, why am I playing Bb? Lol

she mistakenly said B#. She meant Bb, because B# enharmonically is equal to C. just like E# enharmonically is F.
super cool! i am doing my school proejct about this, how did you create the graph with matrices?
Hi Niroda! Sorry for the late answer.. I did it in Photoshop, then exported into Final Cut Pro X.
Dumb question: what is the piece that she’s playing in the begginnig?
Marino Oliveira there are no dumb questions..... only dumb people.
an argument for tempered tuning ?
Great info!!!
love it!!
ill study this video great info
1:47 so there are basically 13 octaves on a piano?
C₁-C₂ to C₇-C₈ = 7, and F₁-F₂ to F₆-F₇ = 6
To be completely honest with you I am not an expert on the subject, I only produced the film for a client of mine who handed me all the information
No, there are 7 octaves and a few more keys. Pianod has 88 keys.... 7 octaves x 12 notes = 84....
If I was with her she would outshine the sun so I fell in love with a godess from above..LOVE..FILLS THE SPACES BETWEEN THE NOTES
:)
No it doesn't! Microtonality does
Great

So then if there are 12 notes why isnt an octive called s dozen?
Because they used to just use 7 notes

I looked this up because of Pythagarus' connection , and mistake, to musical note intonation
Bodhayama first introduced pythagoras
Theorem.
Explain me please
No. It was known in Mesopotamia before 1800 BC.
Looks very young for 50
where can we find more about her

Pretty sure she played a wrong note at the very end of the video while she played Chopin's Raindrop Prelude.

I hate it when she over pronounce S
No, no, no, get off the Web. Your English is not good enough. Get back and learn, BEFORE you think you can teach.
