Derek Showard,[1] better known by the stage name GrandMixer DXT, is an American musician, and the first DJ to use the turntable as a musical instrument.
Widely recognized as a pioneer, Grand Mixer DXT is credited as being the first turntablist.[citation needed] He was the first person to establish the turntable as a fully performable and improvisational musical instrument (Alberts 2002).[full citation needed] Especially important is his technique of altering the pitch of the note or sound on the record.
