Diary of a Degenerate: Mapping Music and Madness by Carlo Gesualdo | classical music

CArlo Gesualdo wrote some of the darkest and most sublime music of the late Renaissance. He also brutally murdered his wife and her lover in their bed. Now be honest: What do you want to discuss first?

Art will always be secondary to brutality, no matter how wonderful madrigals and sacred music may be. Gesualdo, Prince of Venosa, had been cuckolded by the Duke of Andrea in a long-running endeavor that became tantamount to tampering with the court. The premeditated double murder in 1590 was a truly horrific case, ending with the public display of their mutilated bodies on the palace steps for several days.

Gesualdo’s career is often reduced to this act, but his end was also horrific. Twenty years later, the prince retreated to his farm to indulge in a life of ritual torment, and is said to have employed servants to beat him three times a day to relieve sleep and constipation. This domestic nightmare included two concubines whose second wife accused him of witchcraft. Their horrific testimonies, extracted under torture, suggest that the family descended into gothic psychosis.

The composer’s disgust was so evident that I was surprised when St. Martin-in-the-Fields called me and asked if I could create a musical theater piece about his life. This year marks the 300th anniversary of the church in central London, and next week my new work, The Death of Gesualdo, opens as a tribute to the place’s bold artistic independence. It features the wonderful Gesualdo Six, who have long since adopted the troubled prince as their name (the first piece the group sang was the composer’s Tenebrae Responsoria). And so we are all now embroiled in dealing with His Dark Materials, and must confront the sticky relationship between Creator and crime.

Gesualdo wrote madrigals, but not the sunny pastoral that characterized his English contemporary Thomas Morley (now a month old, he was a lover and his girl). If this type of writing had been written by him, we would have succeeded in separating the art from the artist. However, Gesualdo was a musician whose melancholy works (Ahi, desperata vita – Ah of hopeless life; Moro, lasso, al mio dolo – I die, alas, in my suffering) could easily score a film about his sordid life. The music and the man easily form a unique, haunting composition – the aural diary of a degenerate person.

At this point, I had to take a moment of moral pause. Is it appropriate to downplay a killer whose music and online standing would be obliterated today?

For me, art is almost always separate from the artist, whether they are obnoxious or not. We cannot identify anti-Semitism in Wagner’s actual scores. Removing Guernica from the canon because of Picasso’s abuse of women is an unbecoming punishment for the crime. To take a less extreme example, if I’m upset by JK Rowling’s stance on transgender issues, banning her books from my daughter’s bedroom will only close the door on both of us. We know so much about artists today – we swim in the details of their biographies – and thus become unwittingly complicit in the contamination of their art. To make matters worse, facts and fiction are becoming increasingly blurred – today’s young and famous artist would be forced to consider that someone may have already created their own fake pornography.

Let me offer myself as an example. In my production, I try to address these issues by linking Gesualdo’s tortured harmonies to traumatic episodes from his life, and linking his musical hallucinations to his descent into psychosis. It’s fun to find patterns and interesting points to join in. Of course, I hope in vain that this will reveal something new and valuable about him.

But high art is at best a Rorschach test—an inkblot. It is not meant to reveal the artist, but rather to reveal us. Frankly, a staging of Hamlet tells us very little about Shakespeare. It hardly tells us much about Hamlet. If it’s an excellent production, it might remind me that it’s been 17 years since I lost my father, and I really, really miss him.

Which is what makes Gesualdo a valuable case study in 2026: here was that rare artist before celebrity culture taught us how to obsess. Centuries before the Internet, this eldest son of Pope Pius IV was born into a life of transparency. His second wife was Eleonora d’Este of the prestigious northern court of Ferrara, the “City of Music”, and the cultural nexus of Europe in the sixteenth century. Murders aside, his nobility, wealth, and role as a leading composer made him the subject of constant gossip—about his sexuality, intelligence, and more—throughout his life.

The murders were a growing scandal, but perhaps most shocking is that they were completely legal; For an Italian prince of his time, an “honour” killing was an expected ritual to restore power. For this reason he escaped punishment and formed a second strategic alliance with the court of Ferrara. But there the whispers intensified, and perhaps as a result, he devoted himself to the solitude of composition. His final years were marked by another decline, this time due to his belief that he was being hunted by the families of his victims.

In my work, the death of Gesualdo, The composer’s fragile psyche forms a toxic alchemy with the public glare that feeds his psychosis even as he produces stunning music. His final years culminated in the Tenebrae Response in 1611 – a self-evident Mass that conflated Christ’s suffering with his own in full. One hears guilt, atonement, and isolation in the sublime dissonances of this haunting masterpiece. He died two years later, a man broken by the position that protected him.

But are any of these links correct?

The fact is that the forms chosen by Gesualdo – the madrigal – were quite typical of his time. He was not among the avant-garde in Florence, nor did he invent opera with Monteverdi in Mantua, but rather wrote elaborate madrigals, a late form on the way out. The method relied on artificiality, complexity, color and dissonance. No one understood this mission better than our Dark Prince. The music world needs to be honest that “psychopathic composer” is an irresponsible omission. But we’ve allowed bloodshed to define his music, haven’t we, and that’s both the problem and the opportunity.

Through my walk on this panel, I’ve come to realize that punishing hateful artists by erasing their art is the wrong lesson from the 2020s. Artists must realize that there is a significant risk that their work will tarnish their reputation. The public must realize that double-clicking on someone else’s suffering is a step too far. As for Gesualdo’s death, he may not reveal anything about it. It could reveal something about me. If it’s good, it shouldn’t matter, because it will reveal something really important about you.
