Acoustic music is music that solely or primarily uses instruments that produce sound through acoustic means, as opposed to electric or electronic means. While all music was once acoustic, the retronym "acoustic music" appeared after the advent of electric instruments, such as the electric guitar, electric violin, electric organ and synthesizer. Acoustic string instrumentations had long been a subset of popular music, particularly in folk. It stood in contrast to various other types of music in various eras, including big band music in the pre-rock era, and electric music in the rock era.

MTV Unplugged is an American television series on MTV. It showcases recorded live performances of popular music artists playing acoustic or "unplugged" variations of songs. The show aired regularly from 1989 to 1999. From 2000 to 2009, it aired less frequently and was usually billed as MTV Unplugged No. 2.0. Since 2009, MTV Unplugged specials have aired occasionally, sometimes through online or subscription only. Episodes and specials have tended to showcase one artist or group, playing a combination of their hit songs and covers.
