More Blues Minor - The Coal, Hard Sax!
This 4 bar mini-etude didn't make the cut, only because it was conceived at a much slower tempo (ca. quarter note = 120) as in, for example, Joe Henderson's "Out of The Night" or "Bags & 'Trane", than the dozen or so in that post.
It does, however contain the same premise; being based on bars 9, 10, 11 and 12 (bVI7-V7-i-i) of the type of medium tempo Minor Blues as those tunes named above.
This one contains a single, four bar phrase, presented in 12 keys, with a 16th note feel.
It works really well as a warmup type exercise.
