"Stone Killers" Part 1
This free PDF lesson is a great endurance and stick control exercise taken from George Lawrence Stone and popularized by Joe Morello in his "Master Studies" book.
Play each line with a metronome at a comfortable tempo 10 times each and move to the next line without stopping. Play it both with and without accents on the downbeats. Make sure your 16th notes are even and consistent. Work up to doing each line 50 times. Once up to 50 times per line gradually increase the metronome tempo.
