Anna Amalia of Prussia held various titles during her lifetime, including Princess and Abbess of Quedlinburg. Born in Berlin, she was one of ten surviving children of the royal family of King Frederick William I of Prussia. Princess Anna Amalia studied harpsichord, piano and counterpoint. Princess Anna also founded a music library collection, which included autographed scores of J.S. Bach and other composers. This collection still exists today (Amalien Bibliothek). This two-movement Divertimento in Bb Major has something for everyone. The melodic and secondary parts are passed equally between the instruments. The piano part is quite playable for a high school student. It has the character of a conversation between friends gathering for a friendly afternoon tea. This arrangement is scored for piano quartet, with a substitue clarinet part in place of violin.
