Answer :
8 Seconds represents when the texture separates into the melody with accompaniment in the First Movement, Allegro by Wolfgang Amadeus Mozart.
The four movements of Mozart's work, written in 1787, are typically performed by a string quartet or a chamber orchestra.
The first movement is written in sonata-allegro form and in G major, and it is divided into three major sections: the Exposition, which contains two themes, the Development, which is in a variety of keys, the Recapitulation, and the Coda. The sonata-first allegro's theme is a cheery, slightly aggressive ascending theme with similar, repeated phrasing in the first movement. There is a brief transitional passage that leads to the second theme in the first movement.
