In the rondo finale of the eighteenth of these works, the meter changes from 6/8 to 2/4 in the winds. The ninth of these works is nicknamed "Jeunhomme," and the final one is in B-flat, following one of these works with a second movement entirely lacking left hand portions. Besides the "Coronation," one of these works possesses a unique adagio in F-sharp minor, and yet another contains a Mannheim rocket in its final rondo following a peaceful, then furiously fast Romanze movement. For 10 points, name this type of work for solo keyboard and orchestra, 27 of which were composed by Wolfgang Amadeu
