Nudge the tempo a few BPM at a time and watch your clean top speed climb.

The four rudiment families

The 40 Percussive Arts Society rudiments group into four families. Start with the single stroke roll and the single paradiddle, then branch out.

Roll rudiments

Roll rudiments build a sustained sound out of singles, doubles, or buzzes.

Diddle rudiments

Diddle rudiments — paradiddles and their relatives — weave singles and doubles together.

Flam rudiments

Flam rudiments add a soft grace note struck just before the main note for a fatter accent.

Drag rudiments

Drag rudiments place two quick grace notes (a ruff) ahead of the main note.
