[1861+; fr 1700s British kit, ''outfit of equipment,'' plus early 1800s boodle, ''lot, collection,'' perhaps fr Dutch boedel, ''property, effects'']
small fiddle with a muted tone, carried by dancing masters in their pockets in the 16th-18th century. A last descendant of the medieval rebec, the kit evolved as a narrow, boat-shaped instrument with usually three or four strings. Later, narrow, violin-shaped kits were also built. Dancing masters used it to play the dance melody and rhythm while teaching the steps.
