Sonata for Two Pianos (Mozart)

The sonata is written in three movements: The first movement 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. Little time is spent in the development section; a new theme is introduced (unlike most sonata forms) before the recapitulation, repeating the first theme. The second movement is written in A–B–A form. The third movement begins with a galloping theme. The cadences used in this movement are similar to those in Mozart's Rondo alla Turca. == Effects on the brain ==

Mozart's K. 448 was the composition used in the original study that led to the theory of the so-called Mozart effect, which posited that listening to the piano sonata improved spatial reasoning skills, later widened in pop-science to an increase in IQ in general. A 2025 research discovered, using Quantitative electroencephalography, that listening to K. 448 enhances verbal working memory performance. ==Recordings==
