Queer revivals of this dance originate from a festival held in Hamburg in 2001. This dance, described as a “sad thought” by one musician, features moves such as tracing figure eights with one’s feet. (15[2])Rudolph (15[1])Valentino helped popularize an “American” (-5[1])variety of this dance that added head (-5[1])snaps. A variant of this dance (15[1]-5[1])divided into phrases like “cross” and “resolution” are part of the widely taught “eight-step basic” for this dance. (-5[2])Performances of this dance in exclusively minor keys (15[1])occur in (*) Finland, (10[2])where (10[1])the largest (10[1])festival (10[2])for this (-5[1])2/2 or 4/4 dance is held. (10[1]-5[1])Accompaniment (-5[1])bands for this dance’s “new” form feature the bandoneón (10[1])accordion. (10[2]-5[1])The (10[2])inventor of that form, (0[1])Astor Piazzolla, (10[1])also added electric (10[1])guitar to this dance which originated from the earlier milonga (10[1])and flamenco. For 10 points, name this partner dance (10[1])from Uruguay (10[1])and Argentina. (10[3])■END■ (10[7])
