A drop or beat drop in music, made popular by electronic dance music (EDM) styles, is a point in a music track where a sudden change of rhythm or bass line occurs, which is preceded by a build-up section and break.
Originating from disco and 1970s rock, drops are found in genres such as EDM, trap, hip-hop, K-pop and country. With the aid of music production applications, drops can vary in instrumentation and sound. Electronic instruments and tools for making drops include oscillating synthesizers, vocal samples, a drum beat, and basslines.
Certain drops can include a "beat-up" (so-named because it is a point where the volume of the foundational kick drum beat is increased, after it has been faded down during a break or buildup) and "climax" (a single, striking drop done late in the track). There are also types of drops which deviate from the standard, such as "anti-drops" (songs in which the chorus is more minimal than the build-up) and consecutive "superseding-drops".
Drops are performed in music festivals and concerts, as pyrotechnics, visuals, and lighting are designed to correspond with the music. At EDM festivals such as Electric Daisy Carnival, drops are accompanied by confetti explosions, fireworks, and light flashes.
