Sinfonie g-moll KV 550 / Sinfonie Es-dur KV 543 is a paired release of Wolfgang Amadeus Mozart's symphonies, both composed in 1788. The works exemplify late Classical orchestral style, employing concise sonata forms, transparent textures and a keen interplay between strings and winds, and they occupy a pivotal place in Mozart's late output by expanding harmonic tension and motivic development within the symphonic genre.
