This exercise works with septuplets (groups of seven notes) using a mixed sticking pattern. Each measure contains two septuplet groups, with accents on the first note of each group. The sticking pattern (RRLRLRR LLRLRLL) creates a flow that challenges your coordination.
Start slow and focus on:
Start at around 40 BPM and increase speed only when you can maintain clean execution of both the sticking pattern and the septuplet timing. This is an advanced exercise that requires patience to master.
