hi i'm looking at this page that has some midi scores on it here and i scroll down to the bottom where the last midi peice is, and the midi playback is nothing at all like the notes i'm seeing. am i missing something?

the first three measures look like scales in the keys of C, Db, Bb - and then ends going from Bb back to C again.  looks a bit sorabjiish.  like you have to assume where the last one or two staff lines go.  the security lies in the fact that the treble clef tells you where G is and the bass clef dot where F is.  i guess he was only putting the lines that the chords were on - but this makes sightreading quite difficult.  you are playing a scale with a chord.  is it possible to hold all the notes of the chord whilst you play every note of the scale.  no.  unless you attempt to use one finger for three notes and another for another four.  it's just wierd.  i suppose pedal could hold the chord - but the sounds are unclear and creates a sort of 'oatmeal' exercise.

*i think sorabji put stop signs everywhere.  of course, when you write in the lines you can sightread it again much better.  i like his creativity - and he makes you think theoretically.  but - is it ergonomic?  is it following typical harmonic changes?  no.  so you have obstacles that are in one sense - unnecessary.  although it does present some good challenges to the brain.  like suduko.

hey, you know more about theory than you let on.  miles davis/sorabji - interesting.

As is said on that very page:

This classic track from the album Kind of Blue is one the easiest-to-follow examples of modal jazz.

The whole track consists of a cycle of five modes, which look like this:

What you see are the chords and the chord scales, which are the base of Miles Davis' Flamenco Sketches.
