Boom bap is a subgenre and music production style that was prominent in the East Coast during the golden age of hip hop from the late 1980s to the early 1990s.[1]

The term "boom bap" is an onomatopoeia that represents the sounds used for the bass (kick) drum and snare drum, respectively. The style is usually recognized by a main drum loop that uses a hard-hitting, acoustic bass drum sample on the downbeats, a snappy acoustic snare drum sample on the upbeats, and an "in your face" audio mix emphasizing the drum loop, and the kick-snare combination in particular.
