Yes.

Haydn was the founder of the Viennese classical music school and the father of symphony. Haydn established all the important forms and techniques of the Viennese classical music school, and later generations only made further additions and expansions. Haydn's band techniques, blossoming woodwind instrumentation, Haydn's string quartet vocabulary and techniques, and Haydn's logical dynamic development and motivational thinking have given endless inspiration to those who came after him.
