Bringing All the Mallets Into Play by Tony Miceli
I frequently encounter students that are working on 4 mallet playing, but they're having trouble bringing the technique into their soloing. The play the head with four mallets and solo with 2.
Bringing all the mallets into play is a difficult but doable task. When you work out 4 mallets over a head you're already working on this problem. All you do then is examine how you used the mallets on the head and start applying it to soloing. It's a process that can be done. In this audio podcast I talk about that.
