"In the labs I teach, the class chemistry feels to me very much like leading a gig or running a show. In this case it's the students rather than the audience giving me the energy exchange; there's a definite back and forth going on. In the performance skills lab, I ask my students to pair up to work on their midterm project as a duo performance. They have to interpret the music, work out an arrangement, and rehearse together, and then perform it for the class. The final is a similar format except that I'm everybody's duo partner. There are no rehearsals; they talk me through it for a minute or two in class, and then we play together. They know it's on them to be able to tell me what they need from me and have an arrangement prepared."
