In Book I, the fundamentals of string playing were introduced, one at a time, with a solid emphasis on the finger pattern of the major tetrachord. Students learned to read music quickly on uncluttered pages, and they gained competency in playing the original songs, as well as music from the classical and folk literature. This gave them a feeling of accomplishment. In Book II, the students learn other finger patterns which enables them to play in more keys. Book II addresses the issues and differences that arise when teaching the four different instruments. For example, a key which is in the best range for one instrument is out of range and more difficult for another instrument. Therefore, in order to teach the four string instruments simultaneously and in unison, many compromises with regard to the pathway and pedagogy must be made. Book II is divided into 12 lessons. Lesson One: Bowing Styles in the Key of D Lesson Two: Repetitive Bowings in the Lower-Octave Key of G Major Lesson Three: Syncopation in the Key of G Major Lesson Four: Hooked Bowings in the Key of C Major Lesson Five: The Key of F Major Lesson Six: The Key of Bb Major; Backward Extension for Cellos Lesson Seven: Violins Shift to Third Position Lesson Eight: New Patterns in the Key of D Major; Forward Extension for Cellos Lesson Nine: Return to the Key of G Major Lesson Ten: Return to the Key of C Major Lesson Eleven: A Dramatic Ending Lesson Twelve: A Review of Bowing Styles
