audio track you are hearing is based on the classic "I Got Rhythm"
by George Gershwin, and represents just one of many possible
applications of these walking bass with chord accompaniments.
It begins with a rubato (free time) solo guitar chord-melody
intro using the chords from the progression. The walking bass
arrangement from our Four On Six series then provides the backup
for the head, done with Wes-style octaves on guitar, followed by
a 32-bar solo before a return to the head and fade.
