As the first movement's Allegro molto moderato begins alternate major and minor chords (in a characteristic dotted rhythm many forms of which will be heard throughout the quartet) and modes dizzyingly, a few bars for each at a time, and the movement becomes more stable only with the introduction of the main lyrical theme at bar fourteen. The first movement is riddled with tremolandi, which also lead into the repeat of the exposition, and contains several other new departures for the composer.
