Drum Rudiments and Paradiddle Stickings

Percussive Arts Society terminology groups rudiments into roll, diddle, flam and drag families. This page focuses on paradiddle-related diddle vocabulary and a wider set of practice cycles; it does not describe all 120 patterns as official PAS rudiments.

R L R R names a hand order. It does not by itself specify sixteenth notes, triplets, accents, ghost notes, drum sounds or phrasing. Keep those musical parameters separate when you practise.

In the circular previews, each pattern ring distributes its S steps across the displayed 4/4 bar. At BPM B, one full visual cycle lasts four quarter-note beats, and each equal step lasts 240 / (B x S) seconds. The 6-, 12- and 14-stroke cycles are therefore practice groupings across the bar, not automatic changes of meter.

• Hand sequence: R/L order.
• Rhythmic subdivision: how the strokes fit the pulse.
• Accent placement: which strokes speak louder.
• Dynamic level: taps, ghosts and full strokes.
• Orchestration: where the strokes are played.

Use rebound where the surface allows it, but do not force one technical school onto every tempo or instrument. The useful test is sound, relaxation and repeatability.

• Keep the taps low after accents instead of lifting every stroke equally.
• Let doubles rebound, then control the second stroke so it does not disappear.
• Practise open-close-open: slow, faster, then slow again with the same sound.
• Stop if speed creates shoulder, wrist or finger tension.

After the hands are stable, distribute accents to snare, toms, cymbals or kick patterns. A rudiment becomes musical when it supports time, phrase direction and style.

• Use the metronome for pulse and tempo ladders.
• Use Rhythm Reading to separate notation from sticking.
• Use Pulse Orbit to visualize displacement and cyclic accents.
• Use Playalongs or Live Looper to test whether the rudiment still grooves in real music.

Most problems are not solved by more speed. Diagnose whether the difficulty is hand order, subdivision, accent height, balance, relaxation or orchestration.

• If the pattern collapses, say R/L aloud before playing faster.
• If accents blur, practise accent-to-tap transitions at a lower stick height.
• If the loop feels uneven, check subdivision before blaming the hands.
• If orchestration changes the time, return temporarily to one surface.
