Sonata for Two Pianos (Mozart)

The Sonata for Two Pianos in D major, K. 448, is a work composed by Wolfgang Amadeus Mozart in 1781, when he was 25. It is written in sonata-allegro form, with three movements. The sonata was composed for a performance he would give with fellow pianist Josepha Auernhammer. Mozart composed this in the "galant style", with interlocking melodies and simultaneous cadences. This is one of his few compositions written for two pianos.
Description.
The sonata is written in three movements:
Allegro con spirito.
The first movement begins in D major, and sets the tonal center with a strong introduction. The two pianos divide the main melody for the exposition, and when the theme is presented both play it simultaneously. Mozart spends little time in the development introducing a new theme unlike most sonata forms, and begins the recapitulation, repeating the first theme.
Andante.
The second movement is written in ABA form.
Molto allegro.
"Molto allegro" begins with a galloping theme. The cadences used in this movement are similar to those in Mozart's "Rondo alla Turca".
Mozart effect.
According to Epilepsy Action, research has suggested that Mozart's K 448 can have the "Mozart effect", in that listening to the piano sonata improved spatial reasoning skills and reduced the number of seizures in people with epilepsy. Apart from Piano Concerto No. 23, only one other piece of music has been found to have a similar effect.
