A group of composers who worked at Mannheim, in the employ of the Elector of the Palatinate Carl Theodor (reigned at Mannheim 1742-78). They were assembled by the musical director, Johann Stamitz, and included many outstanding figures, such as Cannabich, Fils, the Toeschis, Stamitz's sons, Fränzl, Wendling and the Lebruns; Holzbauer was Kapellmeister, 1753-78. Burney called them ‘an army of generals equally fit to plan a battle as to fight it’; Schubart wrote that ‘no orchestra in the world has ever excelled the Mannheim’. The orchestra developed a new range of effects which the Mannheim composers exploited, especially in their symphonies. Their crescendo was particularly famous; so were the ‘Mannheim sigh’ (an appoggiatura figure) and the ‘Mannheim rocket’ (a leaping triad). Mozart and other composers were influenced by the Mannheim School, who made important contributions to the development of the orchestra and the history of the symphony.
