Could a modern workplace regulation really specify the cleanliness of underwear? In the 18th century, it did. When Joseph Haydn entered the service of the Esterházy family in 1761, his contract covered not only his musical duties but also meticulous rules for his appearance: he was to appear always in uniform, with white stockings, his hair tied in a queue or worn as a guest wig—and he had to ensure his undergarments were impeccable.

Thus, the musician served the court not only with his music but also by reflecting the princely splendor through his appearance. In addition to the scores, clean underwear was part of the “job description”—because in the 18th century, harmony began with the unseen details.
