Here's a selection of patterns taken from the transcriptions of wellknown musicians. The use of patterns adds interest to an improvisation by keeping the listener guessing as to how the pattern will evolve and how it will then merge back into the composition.
Some of these patterns also show how the improvisor introduces and finishes a phrase.
Where two or more chords are shown for the same (or slightly altered) pattern one can often play the pattern over just one chord. For instance, the pattern below can be played over a Dm7 or a G7 chord. Same for the HANCOCK: ALL BLUES PATTERN.
one can choose a different chord altogether. For Fm7 (ex 2) we could
try Cm7 or G7+ or Bb
