Bass drop

A drop in popular music, especially electronic dance music styles, is a point in a music track where a switch of rhythm or bass line occurs and usually follows a recognizable build section and break.

The term "drop" comes from the composer, DJ or producer "dropping in" the primary rhythmic and musical elements previously hinted at all at once. According to NPR, a drop is the "...moment in a dance track when tension is released and the beat kicks in..., releasing the enormous energy accrued during a song's progression...[; after the] momentum build[s,] the pitch rising, the tension mounting, bigger, louder, until suddenly — the drop."Billboard magazine states that the "drop" is the "...moment of instrumental build[-up] when the bass and rhythm hit hardest. It's why arenas full of people suddenly start jumping up and down." Related terms, typically describing certain types of drops, include a "beat-up" (so-named because it is a point where the producer/DJ increases the volume of the foundational kick drum (bass drum) beat, after having faded it down during a break or buildup) and "climax" (a single, particularly striking drop done late in the track).

The drop "...grew out of '70s rock". A subtype of the drop, the bass drop, was used in the Miami bass subgenre of hip hop music in the 1980s. The bass drop was produced using the Roland TR-808's deep drum machine kick drum sound. Since then, the TR-808 bass drop has been incorporated into a number of hip hop and electronic dance music genres, either produced by a TR-808 or using a sample of a TR-808 bass drop. The use of "drops" "...developed in the 2010s through the EDM festival anthem: simply called "the drop."
