Joseph Haydn, the legendary composer of the Classical Era who is regarded as the father of the symphony, also explored interesting combinations in his chamber music. In addition to concert music, Haydn wrote music for use. These works include his numerous divertimenti, music for baryton (a bowed string instrument that fell out of favor after the 18th century) for Prince Nikolaus Esterházy, and duos for varied pairs of string instruments, such as a pair of violins or violin and viola. The substantial number of string duos by Haydn are listed in the Dutch musicologist Anthony van Hoboken’s Catalogue of Haydn’s Works in the sixth section.
