Based on the etudes by world-renowned pedagogue Roland Vamos, this collection of double-stop exercises fill a void in the literature of technical exercises for cellists. These etudes feature a systematic series of fixed double-stops that enables the player to practice and master every possible combination of finger patterns across two strings without shifting. Mr. Vamos says of the book, "The most important accomplishment is the development of a strong left hand... These exercises, when practiced slowly and carefully, will help to develop a keen sense of pitch and intonation." Adapted for cello by Horacio Contreras, teacher, chamber musician, and recitalist.
