"I work with my students to think musically, not just think about playing the exact notes or the exact time. Whatever you're laying down as the primary timekeeper, to make the time and the musical sense correct, it needs to have a musical purpose. When I teach a student to play a Bach piano piece on a marimba, for example, I first get them through the notes—to know how to read the music and use their hands mechanically. Then I ask them to play it musically—to make it breathe so it's not just notes and mechanics. I want my students to be aware of their dynamics, their musical presence, and the texture of what's going on around them."
