First Position Etudes for Strings is written for the second year string class or string orchestra. The etudes are to be started when the string group reaches Page 10 in Volume I of the String Builder. They may, however, be used in conjunction with any standard string class method, as this book is a complete unit in itself and may be used separately for class or individual instruction. The string parts are played in unison with piano accompaniment. Each etude is interesting and has its specific technical value for the left hand and for the bow arm. Published for violin, viola, cello, bass, piano accompaniment, and teacher's manual.

The Belwin String Builder is a string class method in which the violin, viola, cello, and bass play together throughout. Each book, however, is a complete unit and may be used separately for class or individual instruction. The material in this book is realistically graded so that only a minimum of explanatory material is required. Each melody is interesting and will provide the basis for a fine left hand technic and bow arm. Available in three levels for violin, viola, cello, bass, piano accompaniment, and teacher's manual.

Compiled from melodies Samuel Applebaum used to teach his students to play their instruments. The melodies are arranged in progressive order from the first three notes students learn to the end of level one in most method books. These melodies may be played as solos or in unison with other string instruments. Michael Katz has produced the accompaniment CD (in traditional, jazz, and rock styles) to motivate students to practice and perform for friends and family.
