Book 3 features more in-depth information about sonatinas (sonata-allegro form) and the classical era. Some titles not easily found in other collections, such as Sonatina in G Major by Le Couppey, and the complete Latour Sonatina in C Major, appear in this beautifully engraved volume. Each sonatina is in its original, complete form. Sonatinas by Fritz Spindler, Johann Baptist Vanhal, Samuel Wesley, Vincenzo Righini and others are included in this book. Each volume contains a thematic index, a music dictionary, and information About the Pieces and Composers" that can be used in program notes."
