ABSTRACT:
The musical scale indicator according to a first preferred embodiment of the present invention is composed of two cooperating parts. A base is provided having thereon printed information pertaining to a particular musical instrument and which, in addition, has printed thereon fingering patterns for playing tones on that instrument arranged in a predetermined sequence indicative of any number of desired musical scales. A slidable, clear overlay is slidably connected with the base. The overlay has printed thereon the letter designations for the musical tones arranged in a predetermined sequence so as to cooperate with the fingering patterns indicated on the base in order to selectively indicate to the user the finger positions on the subject musical instrument that will produce the tones of a selected musical scale and simultaneously the finger positions on that instrument that will produce those tones.
