MUSIC V is Max Mathew and J. Miller's synthesis program, prepared by Bill Schottstaed for gfortran, with further additions and fixes by Victor Lazzarini.

MUSIC-N refers to a family of computer music programs and programming languages descended from or influenced by MUSIC, a program written by Max Mathews in 1957 at Bell Labs. MUSIC was the first computer program for generating digital audio waveforms through direct synthesis. It was one of the first programs for making music (in actuality, sound) on a digital computer, and was certainly the first program to gain wide acceptance in the music research community as viable for that task.

Music V, created in 1967–68, is the most widely used sound-synthesis program to have been developed at Bell Laboratories. Music V consists of computer models of oscillator and amplifier modules, plus procedures for establishing interactions among the modules.
