The arpeggione is a six-stringed musical instrument, fretted and tuned like a guitar, but bowed like a cello, and thus similar to the bass viola da gamba. It enjoyed a brief vogue after its invention around 1823, by the Viennese guitar maker Johann Georg Staufer (1778-1853). The only notable piece extant for the instrument is a sonata with piano accompaniment by Franz Schubert, but this is now more commonly played on a cello.
