Piano Concerto No. 27 (Mozart) - Instrumentation and Movements

Instrumentation and Movements

The work is scored for flute, two oboes, two bassoons, two horns, solo piano and strings, which makes it thinner than Mozart's other late concertos, all of which except for No. 23 have trumpet and timpani. It has the following three movements:

1. Allegro
2. Larghetto in E-flat major
3. Allegro

Although all three movements are in a major key, minor keys are suggested, as is evident from the second theme of the first movement (in the dominant minor), as well as the presence of a remote minor key in the early development of that movement and of the tonic minor in the middle of the Larghetto.

Another interesting characteristic of the work is its rather strong thematic integration of the movements, which would become ever more important in the nineteenth century. The principal theme of the Larghetto, for instance, is revived as the second theme of the final movement (in the 65th measure). The principal theme for finale was also used in Mozart's song "Sehnsucht nach dem Frühling" (also called "Komm, lieber Mai"), K. 596, which immediately follows this concerto in the Köchel catalogue.

Mozart wrote down his cadenzas for the first and third movements.

Simon Keefe has discussed the concerto in detail, with emphasis on the distinctive character and experiments in style of the concerto compared to Mozart's other concerti in this genre.
