发明名称 Fingering display for musical instrument
摘要 For a musical instrument, a fingering display apparatus that includes a number of electrical switches manually operable to designate a desired musical note, either alone or as the root note for a desired scale or chord. For each of the notes designated by the switches, means are provided to activate a sub-display showing all of the possible fingering positions for that note. If a scale or chord is designated, then all of the fingering positions for all of the notes of the entire scale or chord are displayed. One form of the display, using small electrical lamps, is mounted on the fret-board of a guitar.
