Instant Music allows the user to make variations on songs played by the software.

As the software plays a song, the player, by moving the mouse up and down (or joystick with some versions), can make variations in the current tones.

In December 1986, Bruce Webster's column in Byte magazine selected Instant Music as product of the month, calling it "an outstanding program."

[1] AmigaWorld gave Instant Music a 1986 Editor's Choice Award, calling it "the most fun you can have with your Amiga and your ears."

The reviewer reported that he had begun to play his electric guitar again with the Amiga as accompaniment.
