The Concerto for solo keyboard in G major, F. 40 (BR A13a-b) was composed by Wilhelm Friedemann Bach, the eldest son of Johann Sebastian Bach. The exact date of composition is unknown, but it is believed to have been written in the 1740s. The concerto consists of three movements: Allegro, Adagio, and Presto. The first movement, Allegro, is characterized by its lively and energetic tempo. The solo keyboard is accompanied by a small orchestra consisting of strings and continuo. The movement begins with a lively and rhythmic theme played by the orchestra, which is then taken up by the solo keyboard. The keyboard part is virtuosic and demanding, with rapid runs and arpeggios. The movement is structured in a typical concerto form, with the soloist and orchestra trading off themes and variations. The second movement, Adagio, is a slow and lyrical piece. The solo keyboard is accompanied by a simple and elegant string melody. The keyboard part is more subdued in this movement, with a focus on expressive phrasing and ornamentation. The movement is notable for its use of chromaticism and unexpected harmonic shifts. The final movement, Presto, is a fast and lively piece. The solo keyboard is once again accompanied by the small orchestra. The movement is characterized by its rapid and virtuosic keyboard part, with the soloist performing rapid runs and trills. The orchestra provides a lively and rhythmic accompaniment, with the strings playing fast and intricate patterns. Overall, the Concerto for solo keyboard in G major, F. 40 (BR A13a-b) is a virtuosic and demanding work that showcases the talents of both the soloist and the orchestra. The concerto is notable for its use of unexpected harmonies and chromaticism, as well as its lively and energetic tempo. The work premiered in the mid-18th century and has since become a staple of the keyboard concerto repertoire.
