Here's a prerequisite for the Shapes and Patterns of Music sight reading. My recommendation is to play these exercises as fast as you can but start at the beginning no matter how proficient you already are. If it's too easy, play it faster!
Set your metronome to quarter note = 300 bpm (faster or slower depending on your level) and play or clap the rhythm pages (pages 1 - 21). This fast pace helps teach your mind and eyes to move ahead. You'll notice that the exercises begin with a lot of space per measure and narrows that space down as you advance through the exercises. Learning to use your time wisely is the key to these exercises so when you have three beats of rests, use that time to prepare for what's to come because the next exercise will have less time to think. In other words… you're learning to use the space - focus on that. Most of the energy and focus while using this book should be devoted to the careful use of space during the rests and preparing ahead. Students often relax their attention as if there’s nothing to do during the rests. A drum stick or mallet should be prepared for the next attack immediately after its previous one; not just before it’s needed.
After working on the first 26 pages (which is only rhythm), you'll notice that this booklet jumps ahead to page 76 (pdf page 27)of "THE SHAPES AND PATTERNS OF RHYTHM". This is where those same rhythms are assigned melodies in the key of C. Now you have to read notes. Again, use the rest space wisely. Set the metronome at a very fast pace and begin. As you advance through the "melody" exercises, you'll have to slow the metronome down as they get more difficult.
These same melodies are transpose to all keys. I recommend first going in the order presented here and then going back and working on keys that give you the most trouble.
Please let us know how these work for you as you progress.
