A method and system of teaching music that uses modified representations of the musical score, an interactive visual feedback describing the musical tones played on a musical device, and the marking of piano keys or other control instrumentalities of a musical device. This system helps students to recognize musical notes and piano keys, and to associate each note with the correct piano key. The modification of the musical score includes a vertical presentation of the musical staves, different colors of the staff lines for different staves, pictographs denoting the sol-fa names of the musical notes, and different representations of the musical notes on or between the staff lines. The marking of piano keys includes the application of colorful labels to distinguish the piano keys and associate them with musical notes and staves. A gradual transformation of the music score back to the standard music representation teaches students to read the standard music notation.
