Note: Try playing the licks in different time signatures and on different beats as well. For example, instead of playing starting from beat 1, see how it sounds starting from beat 2, or perhaps the "and of 3" or "e of 1, etc. This is in so many ways more challenging and sounds way more sophisticated than just trying to play it as fast as possible. Taking the chromatic approach is all about phrasing and how you place the line. Play these too fast and they're apt to sound boring, fast!
