World-renowned soloist and Professor of Viola at The Bienen School of Music at Northwestern University, Helen Callus presents her highly successful, comprehensive, multi-point system of creating a solid foundation for left-hand technique. One-Step Scale System for Viola contains insights that Callus has used with her students for the past 25 years. The thorough system has been refined and rewritten to create a trim but thorough program for all ages - from the early student to the advanced. Scales, double-stops, intervals and other musical aspects are examined with the goal of achieving mechanical/technical flexibility one needs before studying a piece. A welcome addition to the study of viola that will remain with each student as they grow.

“A wonderful and exceedingly practical method to help facilitate a good hand frame in order to develop better intonation. This book by Helen Callus should be an important part of every violists music library.” Ivo van der Werff, Professor of Viola, The Shepherd School of Music, Rice University.

“Helen Callus is a modern-day Sevcik! The insightful practice suggestions for these exercises should be required reading for every string player at every level. The is an important addition to our technique arsenal.” Peter Slowik, Robert H Wheeler, Professor of Viola, Oberlin College & Conservatory of Music.

“Every teacher, student and professional should know about this book and make it a part of their daily regimen.” Roberto Diaz, President and CEO of The Curtis Institute of Music. Former Principal Viola of the Philadelphia Orchestra.
