ABSTRACT

As an adolescent, Mozart transformed three piano sonatas by J.C. Bach into piano concertos, effectively teaching himself how to write concertos. This lesson plan involves the first movement of one of the J.C. Bach sonatas, op. 5 no. 2 in D major, and its corresponding concerto setting by Mozart, KV 107 no. 1. Students will become better equipped to analyze the form of Classical-concerto first movements by, first, analyzing J.C. Bach’s original solo movement; next, designing their own hypothetical concerto movement based on the sonata; and finally, encountering Mozart’s arrangement.
