Comping with two mallets
I see two-mallet players comping all the time, but all the instructional material calls for at least three mallets.
I've seem people hit the same note an octave apart, put a full step in between, etc. I also read about the third/seventh idea. Anyway, there are a lot of combinations in an octave that sound different. What combinations (or intervals) would best correspond to various chords?
Any tips for comping with two mallets?
