A document from the master class by Jeff Moore and Jim Yakas (with the Madison Scouts Bass Line) at University of Central Florida music department. Document analyze problems in performance and suggest solutions. Good for every kind of drummer, anyway

Eg:
A. Rhythmic Interpretation

1. Rhythm is played incorrect (open, closed, out of time), individual cannot play rhythm properly alone and/or rhythm is distorted when split.
2. May be caused by depending on listening only and “fitting” into the ensemble. *Individual should be able to play their part in time with metronome, then eventually be able to simultaneously play and listen for balance and flow.
3. Solution to problem
1. Play eighth notes on the right hand unison, then down the line (individually) have them play down beat orientated two or three beat patterns. Then do the same for “e’s” and “ah’s” (switching the line to their left hands). This will help the players realize any individual inconsistencies.
2. Play the split with first note only (to fix the entrance problem)

Other stuff:

B. Timekeeping
C. Balance
D. Coordination/Independence (feet and hands)
