Playing in Keys for Violin, Book One teaches the beginning violin student to play in first position in C, G, and D major. By focusing on areas where students typically struggle to adjust to a specific key (for instance, knowing whether to play high or low 2nd finger on each string), the book builds a deep knowledge of the keys; sharps and flats are presented as vocabulary in a language. With carefully graded exercises and short pieces, this book is a valuable addition to the beginning violin repertoire, giving teachers a much-needed tool for teaching keys. Playing in Keys for Violin, Book One is appropriate for beginning and early-intermediate violin students, as well as adult learners. This book works well along with Getting in Shape for Violin and Warming Up for Violin, Book One.
