In 1826, near the start of his career, Mendelssohn wrote a concert overture (Op. 21). In 1842, only a few years before his death, he wrote incidental music (Op. 61) for a production of the play, into which he incorporated the existing Overture. The incidental music includes the world-famous Wedding March. The German title reads Ein Sommernachtstraum.
