Hip hop production is the creation of hip hop music. While the term encompasses all aspects of hip hop music, it is most commonly used to refer to the instrumental, non-lyrical aspects of hip hop. This means that hip hop producers are the instrumentalists involved in a work. Modern hip hop production uses samplers, sequencers, drum machines, synthesizers, turntables, and live instrumentation. A hip hop instrumental is casually referred to as a beat, and its composer is casually referred to as a producer or beatmaker. In the studio, however, a hip hop producer also functions as a traditional record producer, being the person who is ultimately responsible for the final sound of a recording.
