The present invention provides a method for operating a musical instrument, especially a keyboard instrument such as a piano. In one embodiment, a keyboard instrument is provided which is operable for producing a musical sound. The keyboard instrument is used in combination with a musical staff on which a musical composition has been recorded. The staff has a structure that corresponds with the arrangement of keys on a keyboard such that notes recorded in spaces on the staff correspond to white keys of the keyboard instrument and notes recorded on lines correspond to black keys of the keyboard instrument. The keyboard instrument is operated by depressing the appropriate corresponding white key for a note recorded on a space of the staff and depressing the appropriate black key for a note recorded on a line of a staff.
