Definition
A paradiddle is a foundational drum rudiment built from the sticking right-left-right-right, left-right-left-left. It alternates single strokes and doubles in a repeating four-note cell.
Example
Say "pa-ra-did-dle" out loud and tap one hand per syllable: R, L, R, R, then mirror it L, R, L, L. The doubled "did-dle" on each repeat is what gives the rudiment its name and its rolling, continuous sound when played at speed.
Why it matters
The paradiddle teaches your hands to move smoothly between alternating and repeated strokes, which is the core skill behind fast fills and balanced grooves. On pads it lets you spread a quick line across two fingers without one hand doing all the work, so you can play faster and longer without tensing up.
How to play or configure
On a 16-pad device, assign one sound to a pad and alternate two fingers using the R-L-R-R, L-R-L-L sticking. Start slow with a metronome and keep both fingers striking at equal volume. Once the pattern is even, accent the first note of each group to hear how a paradiddle can voice a backbeat. Then split it across two pads to turn the rudiment into a real drum fill.
