I’ve recently come upon a great book that is a fantastic tool for developing your chops. Daily Drum Warm-Ups: 365 Exercises to Develop Your Technique — includes an exercise for every day of the year. The book covers essentials such as: rudiments, patterns, weak hand builders, triple strokes, finger control, odd-time signatures and much more. Drummers will improve their speed, dexterity, accuracy, coordination, and dynamic control, while developing their stylistic repertoire. The accompanying CD includes all 365 warm-up exercises, plus 20 foot ostinatos that can be used as play-alongs, and five brush examples. It’s also enhanced so Mac & PC users can adjust the tempo without changing pitch. Best of all the book starts out simple and then builds on itself so it’s great for beginners to intermediate and advanced students.
