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".
