Gesualdo's published music falls into three categories: sacred vocal music, secular vocal music, and instrumental music. His most famous compositions are his six books of madrigals, published between 1594 and 1611, as well as his "Tenebrae Responsoria", which are very much like madrigals, except that they use texts from the Passion, a form (Tenebrae) used by many other composers. As in the later books of secular madrigals, he uses particularly sharp dissonance and shocking chromatic juxtapositions, especially in the parts highlighting text passages having to do with Christ's suffering, or the guilt of St. Peter in having betrayed him.
