The role of the Mannheim school's composers in the evolution of the classical symphony is thus significant, although most scholars now agree that these changes occurred nearly simultaneously at various other centers, e.g. in Berlin and Vienna. Their influence on the evolution of the classical music period is due to the reputation of the ensemble at one hand, and on the other hand to the fact that the compositions of the Mannheim school's composers were published in Paris and London as well, some of their works even multiple times of different publishers.
