The study of double-stop octaves on the cello, for advanced cellists, continues in Octaves for the Cello, Book Three. Exercises and short pieces link the A and D octave hand positions learned in Books One and Two with the new "high A position," near the end of the fingerboard. Teachers can use this book to train their students in advanced double-stop playing on the cello before they are required to play octaves in solo literature, or as a technique supplement for students already playing octaves in cello literature. Professional-level cellists can use this book to refine and update their skills. This book can be followed by Octaves for the Cello, Books Four and Five.
