ABSTRACT:
An apparatus for teaching a person to play a musical instrument, particularly a keyboard instrument. The chord and melody notes of a musical passage are stored in a memory in the form of chord words and melody words each comprising a predetermined number of data elements. The data elements in each chord word represent all of the chord notes for a bar of the musical passage and in addition an indicator element which indicates whether the next word is a chord word or a melody word. The data elements in each melody word represent a melody note and timing for a bar of music and an indicator element. The data words are read out of the memory in a sequential manner. Each chord word is transferred into a chord storage register where it is held until the chord is correctly played. The melody words for the particular chord are transferred into a melody storage register at a predetermined rate depending on the timing data in each melody word. Each storage register includes display means for visually displaying the notes contained in each chord and melody word. The transfer of chord and melody words associated with a particular bar of the musical passage into their respective storage registers is halted unless the chord is correctly played.
