The sound comes from the Roland TR-808 Rhythm Composer, a drum machine released in 1980 that created its cowbell with synthesized square waves rather than a sampled metal bell. Producers in electro, hip hop and Miami bass adopted the 808 cowbell in the 1980s for its pitched, melodic quality, and it later became a staple of trap and internet beat making. Because modern producers and soundboard users can pitch it to match a melody, the short hit remains popular decades after the original hardware was discontinued.
