Like many fine musicians, a teacher's instructions do not imprint a carbon copy on the student, but rather the student blends the teacher's lessons with the student's own voice.
I particularly enjoyed the first one. It seemed reminiscent of jazzy type stuff being played in a 40s Hollywood bordello!
That’s a hard one to answer, a bit of both as I recall. The piece was a humorous reaction to what I perceived as the noxious materialism of my work environment and its morally blind executives. This underlying spirit drove the musical creation but the specific words were superimposed afterwards, in pretty much the same way as I allow my brain to attach meanings to my improvisations after the creative event, which is essentially abstract. There are exceptions though, of course, rules are for fools.
