Franz Joseph Haydn (1732-1809) shaped the Classical era as one of its most prolific and inventive composers. Working first at the Esterházy court in Hungary and later in Vienna, he refined the symphonic form, wrote over 100 symphonies, and brought structural sophistication to nearly every genre he touched.
Haydn's choral works reveal his gift for combining learned counterpoint with direct emotional communication. He composed cantatas, masses, and secular choruses for various occasions, each one demonstrating his ability to write idiomatically for voices while maintaining the orchestral brilliance that defined his instrumental music.
