This is a really useful collection of studies for anyone who wants to get really secure in their use of different positions. None involve any position changing, but instead focus entirely on a single position at a time. I strongly recommend this approach for really developing confidence in second position in particular, which so easily gets overlooked. The other books in his 100 Etudes, Op. 32, are also very useful, especially those for position-changing and for double stops.
"Jan Hanuš Sitt, known as Hans Sitt, (21 September 1850, Prague – 10 March 1922, Leipzig), was a Bohemian-German violinist, violist, teacher, and composer. During his lifetime, he was regarded as one of the foremost teachers of violin. Most of the orchestras and conservatories of Europe and North America then sported personnel who numbered among his students."
