The composition of early symphonies was centred on Milan, Vienna, and Mannheim. The Milanese school centred around Giovanni Battista Sammartini and included Antonio Brioschi, Ferdinando Galimberti and Giovanni Battista Lampugnani. Early exponents of the form in Vienna included Georg Christoph Wagenseil, Wenzel Raimund Birck and Georg Matthias Monn, while later significant Viennese composers of symphonies included Johann Baptist Wanhal, Carl Ditters von Dittersdorf and Leopold Hofmann. The Mannheim school included Johann Stamitz.
