ABSTRACT:
A chromatic tuner display is provided for indicating a relative difference between a pitch of a sound and a pitch of a desired note of a musical scale. The display comprises a base member, a predetermined point on the base member corresponding to the pitch of the desired note, and a colored light arrangement for visually representing the pitch of the sound. The colored light arrangement is mounted on the base member and includes a plurality of illuminative letters corresponding to notes of the musical scale, and a plurality of additional illuminative characters positioned on the base member between adjacent letters corresponding to sharp and flat variations of the notes represented by the letters. An illuminated letter or an illuminated letter and character combination represents the desired note. The colored light arrangement also includes a plurality of opposing pairs of colored light devices for visually indicating whether the sound is above or below the pitch of the desired note, each light device within a given opposing pair being disposed on an opposite side of the predetermined point from the other light device within the given opposing pair. Each opposing pair has a specified color for visually indicating the relative difference in the pitch of the sound from the desired note. The colored light arrangement may indicate whether the note corresponding to the pitch of the sound is a standard guitar note or a non-standard guitar note, and may also indicate whether the pitch of the sound is within a first predetermined range from the desired pitch smaller than a second predetermined range of about .+-.2 to 3 cents from the desired note.
