Johann Michael Haydn

Johann Michael Haydn (1737-1806) was an Austrian composer of the Classical era, best known for his contributions to choral, orchestral, and chamber music. He was the younger brother of the more famous composer Joseph Haydn. Johann Michael spent much of his career in Salzburg, where he served as a musician in the court of the Archbishop Colloredo.

His notable works include symphonies, concertos, and a significant number of sacred choral compositions, such as the "Missa in C" and various settings of the Mass. He also composed over 60 symphonies and numerous chamber pieces, which reflect the stylistic transitions of the time.

While he never attained the fame of his brother, Johann Michael Haydn's music was influential in the development of the symphonic form and choral writing in the late 18th century. His works were performed by prominent musicians of his time and contributed to the musical landscape that would lead into the Romantic era. His influence can be seen in the works of later composers, including Wolfgang Amadeus Mozart, who acknowledged Haydn’s contributions to choral music and symphonic structure.
