An all-time best seller, the Belwin String Builder is a string class method in three parts in which Violin, Viola, Cello and Bass play together throughout. Each book however, is a complete unit and may be used separately for classor individual instruction. The material in the book is graded realistically so that only the minimum of explanatory material is required. Each melody is interesting and will provide the basis for a fine left hand technique anda strong bow arm.
