The Telemark is a ballroom dance step; in waltz competition, it is in the Silver syllabus.
[1] The term Telemark is borrowed from skiing, in which a turn is generated by a forward leg motion.
However, the closed Telemark ends in closed position, while the open Telemark ends in promenade position.
[2] The closed Telemark can be followed by a natural turn, natural spin turn, hesitation change, or forward lock.
[1] The open Telemark can be followed by an open natural turn, a chassé from promenade position, cross hesitation, wing, or left whisk from promenade position.
