ABSTRACT:
The invention pertains to musical teaching aid devices for fretted instruments such as guitar. The enclosed invention is a device in which the user builds a desired chord and is taught the form and the spelling of the chord by the use of a special embodiment which contains a perforated top piece plate in which strings and frets are represented by indica, and the bottom piece plate has indica on both sides. The top side containing indica representing the names of the musical notes which are viewed through the top perforated piece, and the back side of the bottom piece contains the chord spelling of a plurality of chord types. In between both the top and bottom piece plates is a frame, which fastens the top and bottom together and serves the purposes of allowing slides to pass through the six given spaces (inserts) in the frame. One slide is given for each string, in which one perforation is centered in the middle of the slide to allow for the selection of a desired note when pushed or pulled through the embodiment. Therefore allowing any type or form of chord to be constructed.
