Emanuel Bachʼs Wq. 118/7 “Minuet and 21 Variations” is a work that fuses the classical beauty of symmetry with the expressive power of the Empfindsamer Stil. This piece takes an elegant and refined minuet as its theme, from which a diverse musical development unfolds through 21 variations. The minuet, which serves as the theme, features a simple and clear melody with a light rhythm, and in the subsequent variations, the ornamentation, harmony, and rhythm become more complex, leading to dramatic musical development. Among the variations, there are brilliantly technical passages and lyrical, sentimental sections skillfully interwoven. Particularly, while the technical movements of the right hand stand out, the harmonic progression of the left hand provides a sense of stability. Each variation expresses a different character, offering the audience new surprises and emotions. Performers are required to have a wide range of techniques and flexibility in emotional expression. Wq. 118/7 is one of Emanuel Bachʼs most accomplished variation works, allowing one to fully enjoy his musical creativity.
