A saxophone teacher instructs music students in the fundamental and advanced techniques of playing the saxophone. In this career, you can specialize in alto sax or tenor sax, both of which have different musical ranges. Your responsibilities are to teach the students how to read sheet music, play the sax, and perform maintenance on the instrument, such as wiping down the brass surface, oiling the keys, and changing the reed. Another part of your duties as a saxophone teacher is to instill an understanding of musical theory as it applies to the saxophone.
