"Music Box Dancer" is an instrumental piece by Canadian musician Frank Mills that was an international hit in the late 1970s. It features an arpeggiated piano theme in C-sharp major (enharmonic to D-flat major) that is accompanied by other instrumentation, which play a counterpoint melody, as well as a wordless chorus, designed to resemble a music box. However, most modern piano music sheets have the song written in the key of C.
