'Trane Changing Tracks - Rhythmic Variety
As mentioned previously in these pages, 'Trane used these four note digital groupings, played in eighth notes, to better negotiate the rapid tempi of several of his classic originals (Giant Steps, Countdown, Satellite, etc), which were based on the descending Maj. 3rd Cycle.
'Trane had an arsenal of these groupings, many of them variations of simple 1235 on Maj. chords (C-D-E-G on C Maj) and b7123 on dominant chords (Db-Eb-F-G on Eb7), as classic examples.
