The Three Sonatinas, Op. 20 can be studied after the Clementi Sonatinas, Op. 36 and are also slightly more difficult than the Six Sonatinas, Op. 55. They prepare the student for study of some of the Haydn sonatas. While several of the sonatinas in this collection are standard teaching repertoire, others are not as readily accessible and present teacher and student with fresh choices for study and performance.
