Abstract: The present invention is directed to a device for teaching students of stringed instruments note locations and proper finger placement on the fingerboard of the instrument. The device may be adapted for use with either a fretted or non-fretted instrument. The device comprises a sheet of autogenously adhesive plastic, such as cling vinyl, within which is a set of dynamically operated markers such as LED lamps or other electro-luminescent devices for indicating fingering locations for scales or chords. Music from any source such as a recording, microphonic pickup, synthesizer, MIDI equipment, or instrument pickups, or the like is the data input to a computer program which can denature the source music into essential components which are then reconstructed into the tonal patterns of a target instrument such as a guitar.

Abstract: The present invention is directed to a device for teaching students of stringed instruments note locations and proper finger placement on the fingerboard of the instrument. The device may be adapted for use with either a fretted or non-fretted instrument. The device comprises a sheet of autogenously adhesive plastic, such as cling vinyl, on which is printed a series of markers indicating note locations, scales or chords. If the device is to be applied to a fretted instrument, the device further has fret openings cut therein, adapted to engage the frets when applied to the instrument. The device is applied to the instrument by inserting it between the strings and the fingerboard, wrapping it around the neck of the instrument and adhering it onto itself along the back of the neck of the instrument.
