Guimpler
GUIMPLER is a universally designed, easy-to-learn musical instrument that significantly reduces the difficulty of playing chords compared to a conventional guitar, quickly enabling simple accompaniment to a song. The instrument keeps the timbre and strumming technique that give the guitar its characteristic sound. Designed mainly as a rhythm guitar for playing accompaniment chords to a melody, it also allows arpeggios (playing the notes of a chord in quick succession rather than simultaneously, usually from lowest to highest) or single notes across a one-octave range (the 12 notes between C4 and C5).
