Here we are for Lick 2!
1. Analyze the accuracy of both hands. The idea is to find a way to make them work together smoothly. Take your time and DON'T force it.
2. Practice using subdivisions. Set the metronome low and increase by subdivision. This way you're covering not only increments of speed, but also musical situations seeing as each subdivision will "feel" different against the tempo. This is a great way to add to your musical vocabulary.
3. Use a stopwatch. As you practice using subdivisions try cycling them by 20 seconds or so. Kind of like a long distance sprinter. 20 seconds on (fast) 20 seconds off (slower). This is a good way to develop muscle memory fast!
