Minimal synth is a form of minimal wave in which the synthesizer is the dominant musical instrument. Minimal synth releases were mostly put out from late 1970s to middle '80s, remaining underground, and were obviously never aimed for MTV/VH1 play. The genre is characterized by dark and moody tones. It has a bleak stripped down sound, with instrumentation consisting generally of raw analog synths, a pulsating drum beat, and cold vocals. This same sort of music without the vocals is also referred to as minimal electronic.
