One piece in this collection has the phrase "sopr'il Soggetto Reale", or "above the real subject," included in its title and is notable for its difficult orchestration for the flute. In addition to that trio sonata, this collection also contains a piece for six voices that was later orchestrated by Anton Webern and a piece in which the second instrument plays the theme backwards, known as a "crab" canon. Inscriptions above some of the pieces allude to "increasing fortunes" and "ascending glory" in unison with the music, and two of the pieces do not contain time signatures, leaving them ambiguous as to how they should be performed. During a trip to Potsdam in 1747, its composer was challenged by this collection's dedicatee to create two fugues on a "royal theme"; those fugues became the two ricercars that open this collection, which also includes ten "riddle" or "puzzle" canons. For 10 points, name this collection of music dedicated to Frederick the Great, a work by J.S. Bach.
