@1:36 every time I see an A#/Bb reference I think of the line from the Goonies during the organ playing scene lol Andie: "I can't tell if it's an A-sharp or a B-flat!" Mickie: "If you get the wrong note, we'll all be flat."
Really enjoying the Bartok stuff! The 2nd quartet includes one of my all time favorite passages in the 1st movement ("Moderato") starting around the 3:20 mark and ending at 3:44. Really love that passage and can remember the feeling I got first listening to it a couple decades ago.
I've thought a lot about so-called quartal and quintal harmony, but never from a twelve-tone angle. Maybe because any stack of seven or fewer fourths contains notes from a diatonic scale (several, if you stick to less than seven notes). I've got some interesting results exploring voice leading between quartal chords and closely-related ones arrived at by moving one voice a semitone in either direction. I cataloged all these possibilities. The smaller stacks can work like a pivot or a bridge to a surprising number of harmonic places, especially if they're placed over a bass not found in the stack of fourths. Consider a four-note stack like B E A D It can also be stacked in fifths: D A E B It can be understood as a 7sus4 chord: E A B D In its most compact form it's Forte set class 4-23 having the prime form 0257. Add one more fourth to the stack and you get a pentatonic scale. Et cetera. Really quite fascinating if you ask me. Yet as I said, I haven't thought much about twelve-tone matters involving fourths. Odd, since these chords can be voiced in ways that don't imply tonality as strongly as triads do.
Good points. Quartal harmony can be very malleable like that. I use the 0257 chord quite a bit in my own work. I just call it a 2/4. One interesting thing about stacked fourths is if you stack 12 of them you get all 12 chromatic pitches. Also a good way to practice anything in all 12 keys - just following the circle of fourths/fifths.
Quartel sextads. Your videos remind me of my music theory classes back in the nineties. Maybe a Bulgarian rhythm video in the future?! Time signature of the week lol
@@Keith_Horn I mainly know classical stuff - off the top of my head Mahler's 10th symphony movement 1 chord, Richard Strauss Salome chord in the final soprano song as well as the Elektra chord in Elektra, some of the chords in Stravinsky's Symphony in 3 movements are cool too!
@ I was just listening to Salome yesterday! I did a video last year on the Elektra chord- great chord! The Stravinsky piece is a good suggestion. Also “the Mahler 10 chord” is a good one. Thanks!
Playing those chords on the electric piano reveals that Bartok was a great jazz musician, way ahead of his time.
Chewy Chordal Goodness™ Good stuff as always, Keith!!!
Please keep showing us all of these amazing beautiful dissonant chords! Wow. I’m learning so much from you. I’m obsessed with crunchy harmony haha.
I am too. Thanks for watching!
You had me at "chewy chordal goodness." Great harmony lesson!
Brilliant!
Loving the Bartok stuff!!
Thanks! A few more coming soon
Hearing the scherzo of the 2nd quartet changed my musical world at 12 y/o

I love that section, too. It's probably a folk melody and he harmonizes it in a much more tonal manner than the rest of the piece. Beautiful section.

I have considered a time signature of the week, actually!
That's definitely a Douglas Adams character
That piano is Chick Corea Elektric Band covering Bartok
You're a big fan of Bartok! :D May I make some chord of the week suggestions?
I am a big Bartok head, for sure. Yes please I love suggestions!

@@Keith_Horn No problem I'll pass on more if I think of any, Salome and Elektra (the 2 horrors) are absolutely addictive pieces I love them!
@@decomprecomp2703 Please do!
Chewy chordal goodness is right.
The chewiest.
