Mark Gilston plays two Bavarian zweifachers on mountain dulcimer: Bayischer Bauer and Wintergrün. a zweifacher is a folk dance which has different measures in two rhythms, waltz (3/4) and pivot (2/4). Each zwiefacher has a different pattern of waltz and pivot steps, and much of the fun of the dance is in figuring out the pattern. Zwiefachers are danced in parts of southern Germany and in the Czech Republic. http://markgilston.com/
