One of the best parts of my job as a music therapist is when I get to share in someone's A-ha moment. These are the times when something that didn't make sense previously all of a sudden is understood and is acted on. I am privileged to share in some of these moments with both my clients (children and adolescents with developmental and psychiatric concerns) as well as with my interns. I love seeing those moments. Recently, my intern has started to realize the power that music brings to a music therapy session. She has moved from the stage of overemphasizing her role in the session to the stage of emphasizing the role of the client in the session, but the role of music is starting to occur to her as well. She is starting to purposefully manipulate elements of music to increase or decrease the effect of music on clients' behavior. She is starting to recognize the changes in behavior that her clients are displaying and is relating those changes to the shifts in the music.
