Kit violin

The kit violin, dancing master's kit, or kit, is a stringed instrument. It is essentially a very small violin, designed to fit in a pocket — hence its other common name, the pochette (French for small pocket). It was used by dance masters in royal courts and other places of nobility, as well as by street musicians up until around the 18th century. Occasionally, the rebec was used in the same way. Several are called for (as violini piccoli alla francese - small French violins) in Monteverdi's 1607 Orfeo.
