Report Tango Appassionata - What Instrument Is This? in Community Posted August 22, 2008 Imeem - Tango Appassionata by Yoko Shimomura I feel really stupid. I can't figure out what the instrument soloing in this piece is. Anyone know? I'm not to keen on folk(?) instruments. It's not an accordion, right? Whatever it is, I really like how it was used in this piece. Thanks much for any help.
