Chopped and screwed (also known as screwed and chopped, slowed and throwed, Houston music, H-Town music, and screw) all refer to a technique of remixing hip hop music by slowing the tempo and applying various DJ techniques such as skipping beats, record scratching, stop-time, and sending portions of the music through stand-alone effects to make a "chopped-up" version of the original.

The style was developed in Houston, Texas, which remains the location most associated with the style. The late DJ Screw, a South Houston DJ, is credited with the creation of and early experimentation with the genre. DJ Screw began making mixtapes of the slowed-down music in the early 1990s. Originally, this process involved mixing two copies of the same record, slowed down either on the turntables using pitch shift or through use of an after-mixer device. Phasing, Flanging and echo effects were originally the result of the two records being played at millisecond intervals.
