The story
You might notice, as you finish turning those pegs, that your guitar feels a little different in your lap. The tension has shifted. Some strings are looser, vibrating with a bit more breath, while others hold steady. You have just stepped into a landscape that musicians often call the Celtic tuning, though its roots stretch much further than the cliffs of Ireland. When you strum all six strings at once, you aren't playing a major chord that feels bright and happy, nor a minor chord that feels heavy and sad. Instead, you are hearing a D-suspended-fourth. It is an open, questioning sound—a harmonic mystery that refuses to pick a side.
The story goes that this specific arrangement of notes, D-A-D-G-A-D, was born from a moment of creative frustration. In the early 1960s, a restless English folk guitarist named Davey Graham traveled to Morocco. He was captivated by the local music, specifically the oud, a fretless, pear-shaped instrument with a deep, resonant soul. Graham wanted to play along with the oud players he met, but his guitar, tuned in the traditional way, felt too rigid and too Western. He needed something that could drone like a desert wind and dance through the intricate, microtonal melodies of the region. By dropping three of his strings down a full step, he unlocked a portal. He found a way to make a wooden box from London speak the language of Tangier.
When Graham brought this tuning back to the folk clubs of Britain, it spread like a secret. It became the backbone of a whole new way of playing. If you listen to the French-Algerian guitarist Pierre Bensusan, you are hearing a man who decided, decades ago, to move into this tuning and never leave. He treats it not as a temporary trick, but as his native tongue. From the folk world, the sound eventually drifted into the heavy, mystical side of rock and roll. You can hear it in the driving, cinematic weight of Jimmy Page’s work with Led Zeppelin, specifically on the track Kashmir, and the intricate folk patterns of Black Mountain Side. It is a tuning that feels ancient and modern all at once.
Because there is no third in this tuning—the note that usually tells our ears if a song is happy or sad—the mood of what you play is entirely up to you. It sits perfectly under the modal melodies of Indian ragas, the haunting licks of the blues, or the rolling hills of a Celtic air.
As you sit there now with your guitar, try one small thing. Let your thumb lazily strike the three D strings—the thickest one, the third from the top, and the thinnest one—letting them ring out like a steady drone. While they hum, use your fingertips to walk a simple melody up and down just the G and A strings. Don’t worry about chords yet. Just listen to how those middle notes shimmer against the low, steady pulse of the D. You might find that the guitar doesn't just sound different; it feels like it has finally found its voice.
