Hal Leonard Melody & Rhythm Permutations by Emil Richards

Emil Richards continues to help percussionists develop their sight-reading abilities with Melody & Rhythm Permutations: More Than 300 Exercises for Mallets and Other Instruments. This book focuses on taking melodies and messing around with their lines, their rhythms, or both! With enough practice, you should be able to play a chart that changes up the melody like it was nothing.
