After returning to his castle at Gesualdo from Ferrara in 1595, he set up a situation similar to the one that existed in Ferrara, with a group of resident virtuoso musicians who would sing his own music. While his estate became a center of music-making, it was for Gesualdo alone. With his considerable financial resources, he was able to hire singers and instrumentalists for his own pleasure. He rarely left his castle, taking delight in nothing but music. His most well-known music was published in Naples in 1603 and from the castle of Gesualdo (with printer ) in 1611. The most notoriously chromatic and difficult portions of it were all written during his period of self-isolation.
