Abstract: The miniature self-controlled musical system includes a plurality of musical instrument assemblies including a drummer, a bass guitar, a guitar and a turntablist. Each assembly represents the selected musical instrument and includes a processor/storage member for storing musical sounds associated with the musical instrument for a particular pre-programmed song. Each musical assembly also includes a speaker member for playing the musical sounds and a control switch for controlling the on-off status of the musical instrument assembly. The system also includes initiating control (selection) elements on each musical assembly for selecting one musical instrument assembly as a master assembly member for a particular pre-recorded song and for communicating control information from the selected master assembly to the remaining musical assemblies to play the particular song.
