Christopher,

Thanks for responding. This is the lesson I was referring to:

To clarify, I am struggling with the timing more than anything. Particularly when it comes to mixing in eighth notes and now triplets and keeping track of the quarter note beats (and the bars) while improvising as you are asked to do in the last part of the lesson.

Is this just a matter of working with a metronome? Are there good practice routines for this?
