Emanuel Bachʼs Sonata in C Major Wq. 65-16 (H. 46) is one of the particularly captivating works among his keyboard music. This sonata, while influenced by his father Johann Sebastian Bach, demonstrates his unique emotional expression and freedom of form. The first movement is characterized by a bright and lively melody, possessing a powerful energy that draws the listener in. The second movement is typically performed at a calm tempo such as Adagio or Andante, evoking deep emotions and an introspective atmosphere. The third movement serves as a light and rhythmic finale, bringing the piece to a close. This sonata well represents Emanuel Bachʼs innovation during the transitional period to classical music and his distinct musical personality.
