The paradiddle-diddle is two singles followed by two doubles: R L R R L L. Unlike the paradiddle, it always starts with the same hand.
Singles on the snare, first double on the rack tom, second double on the floor tom.
Played fast around the kit, the paradiddle-diddle is behind many famous fills. Once it’s smooth, try moving the doubles to different drums.
