[2] Some believe, however that Mozart wrote this and the other sonatas during a summer 1783 visit to Salzburg made for the purpose of introducing his wife, Constanze to his father, Leopold.

The second theme (m. 41) begins in the dominant key of C major, is in galant style, and is immediately restated in varied form (m.

The development section begins at measure 94 with a new melody, focusing on the transitional passage between the second and closing themes in the exposition.

In the 1994 film Immortal Beloved, Giulietta Guicciardi is heard playing this piece during a piano lesson with Ludwig van Beethoven.

There is a change of character in measure 16 where the music is marked p dolce and the right hand has a simple melody embellished with ornamentation and back-and-forth contrasting legato to staccato articulations.

Measure 22 displays yet another character change, where both hands are playing in unison (one octave apart) forte and staccato while moving in an ascending sixth sequential pattern.

Throughout the entire exposition, Mozart uses the model sequence technique, passages of broken chords, parallel motion, scales, and contrasting dynamics and articulations.

The first half of the development uses the model sequence technique, repeating a 4-measure idea of continuous 16th notes constructed of a descending scale, followed by parallel sixths between the left and right hand lower voice, followed by a broken dominant seventh chord.

The remaining recapitulation presents the same thematic ideas as the exposition, just in slightly altered versions.
