Actually written in the 1970's, these exercises were developed on marimba from ideas I became aware of from my study of the piano. They will help the marimbist develop a sense of muscle memory for where the notes on the keyboard are, and how far the distance between notes is. Therefore, when reading music and playing, the marimbist will feel more confident of where the notes are, while looking at the music. Also included are some of my ideas for how to practice creatively. There is a section for two and four mallets, as well as some interesting exercises that are not so much related to ideo-kinetic concepts.
