Sonata in A minor for flute solo (Wq 132)

C.P.E. Bach: Sonata for flauto traverso in A minor (Wq 132) is one of the most significant works for flute solo, which was composed around 1747, while Carl Philipp Emanuel Bach resided in Berlin (rather Potsdam) and was employed as a chamber harpsichordist by German King, Frederick the Great. Since the music composed for the king weren't allowed to be published at that time, the sonata became publicly available only in 1763. The sonata in A minor consists of three movements: Poco adagio, Allegro and Allegro. In addition to baroque style, which was influenced by Carl Philip Emanuel's father Johann Sebastian Bach, the sonata has some features of so-called Galant style, characterized by slow harmonic motion.
Another significant feature of the A minor sonata is that C.P.E.Bach used so-called Silence technique, leaving twice and entire measure without notes. Since there are no accompanying instruments in original score (there are some modern versions where flute is accompanied with piano), there is complete silence in the first (measure 91) and the third (measure 93) movements.
