Thumbposition: Practice Material
On this page can be found links to a lot of practice material (exercises, studies, and repertoire excerpts) for using the Thumbposition, in all the fingerboard regions. A lot of the exercises can be usefully practised in different keys without any changes in fingering, but as we move down into the Neck Region, the use of thumbposition usually becomes more and more uncomfortable because the distances between the fingers become larger.
