How did the music of Joseph Haydn and Wolfgang Amadeus Mozart influence Gioachino Rossini’s early compositions?

Gioachino Rossini recognized the importance of the German school of composition early in his career, specifically identifying new musical elements introduced by Joseph Haydn and Wolfgang Amadeus Mozart.1

These influences were instrumental in shaping Rossini's development as a composer, and they are notably reflected in the early cantata he wrote for Bologna’s Philharmonic School, which was performed in 1808. By integrating these stylistic advancements, Rossini moved beyond traditional Italian operatic conventions, eventually helping to define the bel canto style and restoring a more balanced, significant role to the orchestra in his compositions.12
