Until the end of the 17th century the violin family also included the tenor violin tuned a fifth above the cello; until the 18th century there was also the violino piccolo tuned one fourth above the violin; besides the Syntagma Musicum of Michael Praetorius shows two types of three string treble violins tuned one octave above the violin called in that work "kleine Poschen" and which seem to be very similar to the later Kit violins or pochettes: see Syntagma Musicum, vol. 2, page XXI
