Bapawappa is a sequence of variations to a simple doublestroke pattern. Apart from the crushes, the lead hand stays basically constant throughout the exercise, although there may be subtle differences in timing and volume/height/velocity from variation to variation, depending on how you choose to interpret different rudiments. For additional practice, try feeling the doubles as ninelets (see the 4/4 Feel variation on page 2, with instructions on how to convert the tempo for your metronome).
