History
Kahnotation was developed from 1930-1950 by Stanley D. Kahn. A prominent figure of the International Tap Association, he instructed tap dance at his San Francisco studio for 45 years, and was dance director for the Ice Follies (nowStructure of the Notation
The notation consists of 82 symbols. Approximately 30 are primary symbols and the remainder are compound derivatives. There is no attempt to indicate style, expression, or any of the other dance nuances. These are left entirely to the discretion of the performer or teacher. The primary symbols define * Weight change * Movement of feet (step, tap, brush, shuffle, jump, hop, chug, slide) * Diacritics (heel, ball, toe, edge) * Hand sounds (clapping & snapping)Primary concept
Weight transference during dance is a key dynamic of balance that must be accurately notated. The primary design concept consists of a vertical or horizontal "stroke" or "shaft", and a barb on either side of the shaft indicating whether a weight change occurs. When the barb appears at the LEFT of the vertical shaft, there is NO change of weight from one foot to the other. When the barb appears at the RIGHT of the vertical shaft, there is a TOTAL change of weight. This group of symbols define STEPS, TAPS, JUMPS, LEAPS, HOPS, and SLIDES.Brush
The second symbol group use "C" shaped symbols indicating the foot brushing the floor over a period of time to produce sound. A brush does not change weight. This group of symbols define SHUFFLES, CHUGS, FORWARD BRUSHES, and BACKWARD BRUSHES.Diacritics
The diacritics indicate the anatomy of the foot involved, dance rotation, and which foot is involved. For example, when combined with a STEP symbol, they can indicate whether the step is on the toe, heel, or flat footed.Miscellaneous
The miscellaneous group of symbols indicate hand clapping, finger snapping, and sounds of feet contacting such as heel drops and toe-clicks, grace taps, etc.References
