One of my guitar students majored in Drama in college. As I progress with her lessons, it is increasingly apparent that many approaches to playing music have a lot to do with what she knows as an actor. One example would be that, much like how any script contains lines more expressive or, arguably, more representative of the plot's importance, musical compositions beg that certain notes, phrases, or harmonic motion be brought to the fore. Much of the responsibility of both the actor and musician, then, is to study how lines and music may contain human emotion. Not only that; the artist must make an evaluation of how the work means to create a sense of discourse and then, of course, adhere to those rhetorical conclusions. I would be happy to discuss this and many other ideas over email and, hopefully, in private lessons. Thanks!
