My first edition of previously unknown sonatas by King Frederick “the Great” of Prussia has just been published by Breitkopf & Härtel and is now available here. The volume contains four sonatas for flute and basso continuo composed by the flute-playing king, who held nightly concerts in his exquisite palace retreat, Sanssouci (meaning “Without Care”). I provide extensive documentation and an introduction to the music, based on my research into the king’s compositional activity and his personal letters. The king’s dramatic, rhetorical, and highly virtuosic sonatas feature heartfelt adagios and brilliant, operatic allegros. The selection presented here represents different stages of the king’s composing career, which he began as crown prince in the early 1730s and continued up until the Seven Years’ War (1756 to 1763). More sonatas are soon to follow!
