Lat's talk about musical independence.
That crazy practice of performing two or more independent tasks simultaneously
I don't catch a lot of saxaphone or trumpet players doing it. It's mostly a practice of the polyphonic instruments: predominantly keyboard, strings, and (yes) drumset.
Some examples of musical independence include: playing melodic phrases over ostinati (repeated figures) on a solo instrument, playing polyrhythmic figures on a solo instrument, and performing contrapuntal phrases (round, canon, and fugue) on a solo instrument.
You know what? You can do all those things on a drumset!... Uh hunh! This is the stuff that fascinates me and I will be positing more on this subject.
