>The guitarre d'amour, or arpeggione as it came to be known, was invented sometime during 1823 or 1824 by the respected Viennese guitar maker Johann Georg Stauffer. The instrument -- a kind of enlarged guitar that could be bowed, cello-style, due to an altered fingerboard -- was by no means a success; within just a few years of its birth it had for all intents and purposes suffered extinction. To music lovers, however, this short-lived instrumental curiosity will be forever remembered as the vehicle for Franz Schubert's Sonata "per arpeggione" in A minor, D. 821 -- a work now played almost exclusively by violists and cellists, although it exists in arrangements for instruments as far afield as the euphonium.
>Schubert composed the "Arpeggione" Sonata in November 1824 shortly after returning from Zseliz, where he had spent his second summer (the first one being in 1818) teaching music to the Count of Esterházy's two daughters. The three-movement Sonata must be altered somewhat if it is to be played on cello or viola: the arpeggione possessed six strings, tuned to the same pitches as a guitar's, and the resulting extended range can cause problems when the piece is transcribed; in most editions, certain portions of the piece are transposed up or down an octave from their original position to avoid the extreme registers. However, Schubert by and large avoided the kind of idiosyncratic arpeggiations that earned the original instrument its nickname, focusing instead on the same focused lyricism that drives a traditional sonata for string instrument and piano; in this way, the work readily adapts to modern performance.
