The arpeggione is a six-stringed musical instrument fretted and tuned like a guitar, but with a curved bridge so it can be bowed like a cello, and thus similar to the bass viola da gamba.

[1] It enjoyed a brief period of popularity for perhaps a decade after its invention around 1823 by the Viennese instrument luthiers Johann Georg Stauffer and Peter Teufelsdorfer.

The only notable extant piece for the arpeggione is a sonata with piano accompaniment by Franz Schubert, D.821, not published until 1871, when the instrument was long out of vogue.

In the 21st century, a revival of interest in the arpeggione has led to the composition of a number of new works either for the instrument alone or within an ensemble.

Composers who have written the largest number of works include the American Dov Joshua Rosenschein,[2] France's Grégory Guéant,[3] and René Mogensen[4] from Denmark.
