Shifting in Keys for Cello, Book One presents studies that move through the positions, focusing on the half and whole steps in each key. This book helps the cellist solidify their knowledge of extended and closed positions in the keys of C, G, D, F, and B-flat. Shifting in Keys is especially helpful as preparation for the patterns found in Baroque repertoire, such as the cello sonatas by Vivaldi, Marcello, and Handel. The exercises extend into seventh, eighth, and ninth positions, making this an ideal study book for late-intermediate students or a helpful warmup book for early-advanced cellists. This is a good book to study after Serial Shifting and might be followed by Broken Thirds (One String) for Cello, Book One.
