Structure
The concerto has three movements:
- Allegro in A major and common time.
- Adagio in F-sharp minor and 6/8 time (in later editions, the tempo is listed as Andante).
- Allegro assai in A and alla breve (in later editions, the tempo is listed as Presto). In Rondo form.
The first movement is in A major and is in sonata form. The piece begins with a double exposition, the first played by the orchestra, and the second when the piano joins in. The first exposition is static from a tonal point of view and is quite concise, the third theme is not yet revealed. The second exposition includes the soloist and is modulatory. It also includes the previously unheard third theme. The second exposition is ornamented as opposed to the first exposition which is not. The second theme has harmonic tension. This is expressed by dissonances that are played on the beat, and then solved by an interval of a descending second. This is also expressed in the use of chromatics in the melody and bass lines which is a source of harmonic tension, as the listeners anticipate the arrival of the tonic.
The second, slow movement, in ternary form, is somewhat operatic in tone. The piano begins alone with a theme characterized by unusually wide leaps. This is the only movement by Mozart in F sharp minor. The dynamics are soft throughout most of the piece. The middle of the movement contains a brighter section in A major announced by flute and clarinet that Mozart would later use to introduce the trio "Ah! taci ingiusto core!" in his opera Don Giovanni.
The third movement is a rondo. It is shaded by moves into other keys as is the opening movement (to C major from E minor and back during the secondary theme in this case, for instance) and with a central section whose opening in F sharp minor is interrupted by a clarinet tune in D major, an intrusion that, according to Girdlestone, reminds one that instrumental music at the time was informed by opera buffa and its sudden changes of point of view as well as of scene.

Famous quotes containing the word structure:
“The philosopher believes that the value of his philosophy lies in its totality, in its structure: posterity discovers it in the stones with which he built and with which other structures are subsequently built that are frequently better—and so, in the fact that that structure can be demolished and yet still possess value as material.”
—Friedrich Nietzsche (1844–1900)
“Just as a new scientific discovery manifests something that was already latent in the order of nature, and at the same time is logically related to the total structure of the existing science, so the new poem manifests something that was already latent in the order of words.”
—Northrop Frye (b. 1912)
“The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.”
—For the State of New Jersey, U.S. public relief program (1935-1943)
