Hear as much music as you can. You need to be familiar with far more music than that which you perform. Try to hear as much music from as many historical periods and cultural sources as possible. Ask your teachers to recommend a listening list for you that covers the various solo, small, and large ensemble repertory in your performance area. Try to make sure that you have heard the major works of all types in the particular area of music that interests you. Listen more to learn the breadth and depth of the repertory than to enjoy what is already familiar. Whenever possible, follow the score as you listen.
