Blessed with a gift for musical invention and structural organisation, Johann Stamitz was one of the pioneering figures in symphonic music before the emergence of Haydn. He drove the development of symphonic form via the assimilation of the new operatic overture style resulting in works of brilliance and skilful orchestration. His Op. 3 symphonies, though not composed as a set, showcase why Stamitz was held in such high regard and was so influential: outer movements fizz with energy, and contain virtuosic string writing with frequent dynamic contrasts, while slow movements are intricate and refined.
