Though easily played on the viola, I gather, the original 1849 Kistner publication didn't (I gather?) list viola among alternates, just horn, cello and violin: "Adagio u. Allegro für Pianoforte u. Horn (ad libitum Violoncell oder Violine) Op. 70" (OCLC1074911487, also see HMB 1849.) Not sure about the autograph manuscript, though! 2604:6000:B484:AF00:B40B:DE66:9331:F208 (talk) 17:34, 5 July 2020 (UTC)[reply]
