4-2-1 Concept for Pit is a base exercise that has endless possibilities. Take this skeleton and apply any variation you can think of, from simply adding in octaves to the craziest 4-mallet permutations in every key. The synthesizer parts come with chord names and progressions to assist the players as the exercise modulates to different keys. Timpani and percussion players get a similar exercise to "8 on a hand" while also incorporating different paradiddle combinations.
