Abstract
Abstract The invention is an aid for teaching the position of notes on a staff in relation to the position of the corresponding keys on the keyboard. A rotatable dial permits the user to select any octave from the periphery of the dial and indicators on the dial direct the user to spaced locations on a musical staff where the notes of a diatonic scale in the selected octave are written. A substantial portion of a keyboard which is divided into numbered octaves is represented beneath the dial to indicate the general area of the keyboard in which the user is working.
