Rhythm Resources
In order to be an outstanding musician, one must understand the importance of knowing how to read rhythm. Below are some recommendations that I have used:
Winning Rhythms by Edward Ayola
Rhythm Vocabulary Charts by Ed Sueta
Count Me In by Darcy Vogt Williams & Brian Balmages
The Rhythm Bible by Dan Fox - This book is designed for jazz, but is great if you are looking for an extra push in syncopation.
Search Rhythm Sheets in a search engine online. You can find many free resources.
Check your local music store for rhythm books.
