J. C. Bach was one of the very few composers Mozart greatly admired. His keyboard concertos opp. 1, 7, and 13 influenced Mozart's piano concertos in the following areas: structural principles of the first movement including the use and expansion of ritornellos and solo sections; the use of wind instruments; the cantabile melodic style of the slow movement; and the use of Minuet or dance, Rondo, or Variation forms in the last movement. Op. 7 particularly sets a model for the newly developed concerto form.
