Emanuel Bachʼs Wq. 118/8 “Canzonetta and Six Variations” is a charming piece characterized by its singing theme and variations. This work is based on a canzonetta (a short and simple song-like melody) and unfolds with a variety of variations. The theme of the canzonetta possesses a light and lyrical character, and in the subsequent six variations, the ornamentation, rhythm, and harmony undergo rich transformations. Notably, each variation expresses different emotions, showcasing the features of the empfindsamer Stil (sensitive style) throughout. The piece includes not only brilliant and technical sections but also introspective and sentimental variations, giving the entire composition a dramatic structure. The harmonic progression in the left hand supports the theme while the right handʼs brilliant movements embellish the piece. Performers are required to have the technique to clearly express the diverse variations and the sensitivity to convey subtle emotional nuances. Wq. 118/8 is a piece that highlights Emanuel Bachʼs creativity in drawing out a wide range of musical ideas from a simple theme.
