Re: Marco Minnemann
err well i guess this post is a few months belated.. but regardless
if you define independance as being to play a co-ordinated rhythm independant of another (ie left hand/right hand.. right foot/right hand) it's impossible to differentiate between actual improvisation (and real independance), and memorized rhythm.
so assume your playing a shuffle, and you displace the upbeat every few bars. while you are obviously doing this independant of the rest of the rhythm, which is consistant, it is likewise possible that you just memorized a few bars, with an upbeat that doesn't fall in the same place
of course it's a fair bet to say someone on marco's playing level can improvise pretty fluently, but you can't honestly say he has excellent independance without being him..
