Summarized by ChatGPT4o from the commentary attached to Sergio Cánovasʼs YouTube video of this piece:
C. P. E. Bachʼs Symphony Wq. 182-2 (H. 658) is characterized by its original structure and rich expressiveness in three movements. The first movement (in B-flat major) is in ternary form, contrasting rhythmic themes with lyrical phrases, and in the development section, rapid parts dramatically intersect with melancholic sections. Unusual modulations enhance expressiveness, and just when the recapitulation seems to begin, it suddenly ends, leading directly into the next movement. The second movement (in B minor) is in ternary form, presenting a richly ornamented lyrical theme, with a modulation to D major in the middle section enhancing its lyricism, but the music abruptly halts and transitions to the next movement. The third movement (in B-flat major) is in a theme and continuous variation form, alternating between fast-tempo themes and lyrical phrases, deepening expression through dynamic contrasts, modulations, and ornamentation. It concludes powerfully with a brilliant coda.
