Abstract: A music teaching apparatus, useful for requiring the student to play notes in correct relative timing and suitable for employment on a piano, includes a holder for sheet music, a continuous transparent web having a plurality of opaque covering sections thereon, such as strips of pressure sensitive tape of substantial width, so as to be capable of covering at least one note "width" and preferably more, with such opaque sections being positioned to permit (and require) continuous reading and playing of the music by the player ahead of the covering sections when the web is moved across the music, and means, such as a pair of vertical cylinders about which the web is held in tension, for continuously moving the web across the music and in contact with it or close to it (so as to prevent optical distortions). Preferably, individual opaque sections extend over a treble staff and a corresponding bass staff but do not extend to other treble and bass staffs. A method of teaching music is also disclosed.
