some of my notes:
+38min (0415) reduced to < 12.5
looking at overall pattern of notes can get a sense of the freestyling.
do the notes seem to go in an unpredictable way?
do they cover very different range?
is there potential of a song in the passage?
for short sections how can we simplify part to be able to repeat theme in piano to build upon idea?
which parts are memorable?
how many times to listen over freestyle concept to begin identifying themes/sections?
does one part like another part following it?
does a section naturally have variety in tempo and feeling?
is there potential to sing to a section?
