Johann Christian Bach's Sonata for keyboard in A major Op. 17/5, CW A11 (T. 342/1) was composed in the mid-1770s. It is a three-movement work that was premiered in London, where Bach was living and working at the time. The first movement, marked Allegro, is in sonata form and begins with a lively and cheerful theme that is immediately repeated. The development section explores the theme further, with the use of chromaticism and unexpected harmonic shifts. The movement ends with a recapitulation of the main theme, followed by a coda that brings the movement to a close. The second movement, marked Andante, is a lyrical and expressive piece in A minor. It features a simple melody that is accompanied by arpeggiated chords in the left hand. The middle section of the movement is in the relative major key of C, and features a more elaborate melody that is played by the right hand. The movement ends with a return to the original theme, played in a higher register. The final movement, marked Allegro assai, is a lively and energetic piece that features a playful and syncopated theme. The movement is in rondo form, with the main theme returning several times throughout the piece. The middle section of the movement features a more lyrical and expressive melody, played in the key of F-sharp minor. The movement ends with a return to the main theme, played in a faster tempo, and a coda that brings the piece to a close. Overall, Bach's Sonata for keyboard in A major Op. 17/5 is a charming and elegant work that showcases his skill as a composer and his ability to write music that is both technically challenging and musically engaging. The work is characterized by its lively and cheerful themes, its use of unexpected harmonic shifts and chromaticism, and its lyrical and expressive melodies.
