How did Joseph Haydn’s early music reflect Baroque, Austrian, and north German styles?

In his early career, Joseph Haydn synthesized three distinct musical traditions to forge his own unique style:1

• Baroque: Haydn was familiar with the complex, "pompous" idiom of the Baroque era, which emphasized rigorous counterpoint. He later incorporated these contrapuntal techniques into his mature works, blending them with Classical symphonic principles.21
• Austrian: He adopted the light, elegant, and "gay" musical style popular in Austria at the time. This influence is evident in the naturalness and humor of his music, as well as his use of folk music for melodic inspiration, particularly in his minuets.21
• North German: Haydn was influenced by the expressive, emotionally charged style known as Empfindsamkeit, championed by Carl Philipp Emanuel Bach. This aesthetic, which favored emotional depth and sensitivity, helped Haydn move toward the more intense, dramatic expressions found in his Sturm und Drang period.21

By simultaneously integrating elements from these three traditions, Haydn eventually transcended his early influences to establish a highly individual and influential musical identity.1
