Giovanni Paisiello was an Neapolitan composer of the Classical era.
Paisiello was primarily an opera composer. His instrumental works are therefore imbued with a similar vocally conceived melodic line, granted they may be lacking in the sophisticated counterpoint and motivic work of Haydn and Mozart's music. This characterization, however, does not do justice to the extreme drama and topical contrast in all his works such as the Piano Concerto No. 4 in G minor. Essentially he had mastered all the techniques which made for good opera, and this made his works widely popular and admired throughout Europe.
