"A very rare example of the work of Hans Krouchdaler (Bern, Switzerland, ca. 1700), who, although residing in Bern, can be thought of as being a representative of the Alemanisch School. He was a pupil of perhaps the most significant luthier of this school, Joseph Meyer, from Pfaffenhausen, Germany."
"knowtes" fingering charts from simplyviolin.com. I don't generally like fingerboard charts because they require 'map-reading' skills and I prefer to spend my time teaching string playing skills. But if the student already thinks in this way, they can find it useful to map out the fingerboard. If I had to have one, I like how this one attempts to show a little of an angled perspective instead of looking straight down at the fingerboard.
