One drop rhythm

One Drop drum pattern  Play .

One drop rhythm is a drumset playing style of reggae, popularized by Carlton Barrett, long-time drummer of Bob Marley and the Wailers, created by Winston Grennan, in which the backbeat is characterized by the dominant snare drum stroke (usually a click produced by hitting a rimshot) and bass drum both sounding on the third beat of every measure in 4/8 time (counting in 4/4 time, the drummer would leave beats one and three open), while beat one is left empty. Thus, the expected hit on beat one is "dropped," creating the one-drop effect. A good example of this drum beat is Bob Marley & The Wailers' song "One Drop", which talks about this rhythm.
