发明名称 Stringed musical instrument
摘要 A stringed musical device for teaching purposes in which a longitudinally extending member having dimensions similar to a guitar neck is provided with a head extending away therefrom with six machine heads mounted thereon for maintaining tension in the associated six strings. Frets are provided on one side of the member and four bridges are used to maintain different sets of tensions in the strings on the fret side and on the reverse side of the member such that fingering or left-hand playing for a normal guitar user may be practiced on the fret side and plucking or strumming may be practiced on the opposed side.
