Abstract
A small lightweight electronic device to indicate the finger positions of a fretted stringed instrument represented by the musical intervals or chords in any key. The device has a series of on-off switches representing each of the desired musical keys and a series of switches representing the individual musical intervals over a desired range. The necessary circuitry is provided between these switches and a display of the frets and strings of the instrument such that the finger positions represented by a chord or series of musical intervals in a selected key are visually indicated on the display. Professional musicians and students or teachers of music for fretted stringed instruments can, using this device, visualize the location of intervals or chords of any key.
Claims13
An electronic device for visually illustrating the finger positions necessary to produce a selected cord in a selected key on a stringed, fretted musical instrument, said device comprising:
- (a) a frame structure including a display means for visually representing the strings and frets of a stringed, fretted musical instrument, said display means having at least two display ranges respectively corresponding to different fret ranges on the instrument;
- (b) indicator means for identifying the instrument frets visually represented in each said display range;
- (c) illuminating means for illuminating areas of each said display range in accordance with the various finger positions on the instrument strings relative to the instrument frets;
- (d) a plurality of key selector switches connected to said indicator means and respectively representing various musical keys such that the actuation of said key selector switches causes said indicator means to indicate for each said display range the particular instrument frets used in conjunction with selected musical keys;
- and
- (e) a plurality of musical interval selector switches connected to said illuminating means and respectively representing various musical intervals such that the actuation of said musical interval selector switches causes said illuminating means to simultaneously illuminate predetermined areas in each said display range in order to provide visual representations of the particular instrument finger positions corresponding to selected musical intervals.
An electronic device for visually illustrating the bar and finger positions on a stringed, fretted musical instrument, and changes which occur when musical intervals corresponding to the illustrated finger positions are transposed from one key to another, said device comprising:
- (a) a frame structure including a display means for visually representing the strings and frets of a stringed, fretted musical instrument;
- (b) illuminating means for illuminating areas of said display means in accordance with the various finger positions on the instrument strings relative to the instrument frets;
- (c) a plurality of musical interval selector switches connected to said illuminating means and respectively associated with various musical intervals such that the actuation of said musical interval selector switches causes said illuminating means to illuminate predetermined areas on said display means in order to provide visual representations of the particular instrument finger positions corresponding to selected musical intervals;
- (d) indicator means for identifying the location of a mechanical bar device relative to the instrument frets represented on said display means;
- and
- (e) a plurality of key selector switches connected to said indicator means and respectively representing various musical keys such that the actuation of said key selector switches causes said indicator means to visually indicate the changes in mechanical bar position necessary to produce changes in the musical key of the instrument.
An electronic device as set forth in claim or 2, wherein said key selector switches respectively represent a chromatic progression of musical keys over an octave range.
