In the Vienna of the second half of the 18th century, in addition to Haydn and Mozart, three symphonic composers, namely Leopold Hoffmann, Carl Ditters von Dittersdorf and J.B. Vanhal helped further the development of the symphony.
Symphony, a lengthy form of musical composition for orchestra, normally consisting of several large sections, or movements, at least one of which usually employs sonata form (also called first-movement form). 1  Symphonies in this sense began to be composed during the so-called Classical period in European music history, about 1740â1820.
