 Together with Georg Christoph Wagenseil and other contemporaries such as Leopold Mozart and Josef Starzer, Monn could be said to represent a school of Austrian composers who had thoroughly studied the principles of counterpoint as practised by Johann Sebastian Bach and Johann Joseph Fux, but also effected a change from the formalistic, imposing and ornate Baroque style to the simpler, more graceful Galante music.Moreover, they renewed the sonata form by expanding the concepts of secondary theme and development.Later on, Michael and Joseph Haydn would develop these concepts to a much greater extent.
