Carefully selected and curated to support teachers and students in their artistic and technical development, the Violin Series, 2021 Edition includes pieces from a diverse range of eras and styles that represent stepping stones to major violin repertoire. Each level is constructed to connect repertoire selections to necessary techniques and corresponding etudes, while illustrating step-by-step connections for developing core skills. Each Repertoire book includes access to quality video and audio recordings by some of North America's finest violinists and accompanists; both performance and accompaniment-only tracks for each Repertoire selection offer students a model for performance practice and the convenience of accompanied rehearsal at home.

Violin Repertoire 4 includes Baroque, Classical, Romantic, and 20th- and 21st-century selections of Johann Sebastian Bach, Natalya Backlanova, Ethel Barns, Harold Birston, Arcangelo Corelli, Franz Joseph Haydn, Ferdinand Küchler, Jacques Féréol Mazas, Eduard Mollenhauer, Yoshinao Nakada, Charlotte Ruegger, Arnaldo Sartorio, and Gerry Thornton. Level 4 introduces new aural challenges with tempo fluctuations and harmonic modulations, while exploring compound meters, syncopation, and hemiola. This book encourages performers to be flexible, as it expands upon hand-frames with extensions, fourth-position fluency, and fingered double stops, while the bow develops stylistic applications of articulations, including off-string strokes.
