Summarized by ChatGPT4o from the commentary attached to Sergio Cánovasʼs YouTube video of this piece:
Carl Philipp Emanuel Bachʼs Symphony Wq. 183-4 (H. 666) is a three-movement work rich in contrast and expressiveness. The first movement (in G major) is in ternary form, presenting a gentle and elegant theme by the orchestra, with flutes and oboes playing a lyrical contrasting motif. The development section features notable modulations, ornamentations, and dynamic contrasts, with woodwinds adding variation to the music. After a brief recapitulation, it transitions smoothly to the next movement. The second movement (in G minor) is also in ternary form, with strings playing a sorrowful theme while the woodwinds remain silent. The middle section modulates to B-flat major, creating a gentle contrast. The theme returns in the recapitulation, leading to a dramatic development before moving to the next movement. The third movement (in G major) is in a free theme and variations form, beginning with a hunting horn-like motif and developing vigorously. Bach skillfully uses sudden stops and abrupt phrase changes, adding contrasts in dynamics and ornamentation, and concludes with a powerful coda.
