All GRIDS share the concept of shifting an embellishment across different partials of a rhythm or rudiment. There are thousands of formulas and combinations utilizing this concept that help supplement drummers seeking to develop accuracy, fluidity, and rhythmic comprehension.

 

A basic 4-2-1 grid could implement single stroke sixteenth notes with a shifting accent:

1. )  Play each pattern four times.

2. )  Play each pattern two times.

3. )  Repeat step 2.

4. )  Play each pattern one time.

5. )  Repeat step 4.

A.)  First Pattern - Accent falls on the downbeat (the first partial or sixteenth note).

B.)  Second Pattern - Accent shifts to the right (or the "e" of the beat).

C.)  Third Pattern - Accent shifts to the next sixteenth note (or the "&" of the beat).

D.)  Final Pattern - Accent shifts to the last sixteenth note (or the "a" of the beat).
