Permutations: Rhythmical Matrix
Some of my upcoming drum lessons will focus on rhythmical permutations and matrices. I’d like to share a rhythmical matrix that divides 8 into three groups — a tool I find incredibly useful when practising standard rock beats on the drums.
This matrix offers a clear overview of all sixteenth notes within a 2/4 time signature, or all eight within a 4/4 measure. It’s a great foundation for creating countless rhythm exercises, some of which I’ll share here soon. If you’ve ever been a student in my drum classes, you’ll undoubtedly know how to apply this matrix in your own practice.
Rhythmical Matrix – 8 divided in 3
Rhythmical matrices act as guiding maps for permutating specific time signatures or rhythmic values. The focus isn’t necessarily on the end result but on visualizing the mathematical structure behind rhythmic variations and combinations.
When dividing a rhythmic value, the divisor can never exceed the value itself — simply because no further variations would exist. The number 8 offers multiple practical options: two groups of sixteenth notes or four groups of eights are the most common. Still, players are encouraged to explore whichever configuration feels most helpful or inspiring to them. Have fun experimenting with the possibilities of this matrix!
