John Coltrane Illustrates the Mathematics of Jazz | American Jazz Music Society

The Jazz of Physics: Albert Einstein and John Coltrane had a lot in common. The so-called “Coltrane circle” or “Circle of Fifths,” but incorporates Coltrane’s own innovations. Coltrane gave the drawing to saxophonist and professor Yusef Lateef in 1967, who included it in the Repository of Scales and

Dear #musictheory lazyfedi: has anyone written up an index of all jazz standards grouped by shared chord progression (modulo substitutions)? Or is that something everyone rediscovers just by working their way through a fake book?

#music and #musictheory geeks, a little help please

I'm transcribing a song in A. The last line repeats, but slightly altered so that the second time through it sounds resolved.

Now here's the thing

The best transcription of the chords that I can make comes up with

Bm A D
Bm F# D

All I can think is that even though Bm F# and D are all in A, my ear has somehow been tricked into thinking the last line is now in D major. Is that a thing?

Or am I even worse at transcription than I think? It's a distinct possibility.

A #Microtonal #MusicTheory question: is there any research or experimentation about scales in 53-ET? For instance, here is a 13-note #scale in 53-ET (notes 0 to 52, 0 is tonic):
a=0 b=4 c=9 d=13 e=18 f=22 g=25 h=28 i=31 j=35 k=40 l=44 m=49 (a=53)
The differences, in steps, between notes, are 4 5 4 5 4 3 3 3 4 5 4 5 4, nicely symmetric.
How many nice-sounding #chords can be found in this scale? If one is allowed to bend some of the notes one or two steps (up or down), which other nice-sounding chords can be found?
Is there a site where I can assign arbitrary frequences to computer keyboard keys (53-ET if possible), and play some #tunes?
