From Wikipedia, the free encyclopedia. Programme music (or program music in US English) is music for instruments which describes something or tells a story. It is the opposite of absolute music which is not trying to describe anything, just the sound of the piece. Programme music was very popular in the 19th century although some programme music was written earlier.
