The story
Imagine the high, dusty plateaus of the Big Island in the 1830s. The air is cooler up there than it is on the coast, and if you listen closely, you can hear the lowing of cattle drifting across the volcanic soil. This was the era of King Kamehameha III, who realized his people needed help managing the massive herds of wild cattle roaming the islands. He invited Mexican and Spanish vaqueros to Hawaii to teach the locals the art of the cowboy. When these vaqueros eventually finished their contracts and prepared to head home, they left behind their horses, their heavy leather saddles, and their Spanish guitars.
But there was a catch. The vaqueros left the instruments, but they didn’t necessarily leave behind the instructions on how to play them. The story goes that the Hawaiian people, left to their own devices, began to experiment with the wooden boxes. They didn't have a tradition of complex European chords, so they did something intuitive and beautiful. They turned the tuning pegs, loosening the strings until the guitar sang in a way that mimicked the natural world around them—the pulse of the surf, the wind through the ferns, and the deep resonance of the mountains.
They called this style Kī hōʻalu, which literally translates to "loosen the key." By slackening the strings into open tunings, a player could strum all six strings at once and hear a perfect, ringing chord. The most famous of these is the Taro Patch tuning, which you have just set your guitar to right now. It is an open G—D, G, D, G, B, and D—and for over a century, tunings like this were kept as guarded family secrets. If a stranger walked into the room while a master was playing, the guitarist might stop abruptly or even retune the instrument on the spot so their specific family "key" wouldn't be stolen.
This private, porch-side tradition finally reached the wider world in 1946 and 1947, when a legendary musician named Gabby Pahinui made the first professional recordings of slack key. His work paved the way for the Hawaiian Renaissance of the 1970s. During that time, artists like Ledward Kaapana, Keola Beamer, and the Sons of Hawaii took these intimate family secrets and turned them into a celebrated concert art, ensuring the loosened key would never be forgotten.
When you play in this style, your guitar becomes a drum and a harp at the same time. As you begin, try this one small thing. Use your thumb to alternate a steady beat between the two lowest strings—your low D and your G. Don't worry about the melody yet. Just keep that thumb moving like a heartbeat, and listen to how the open strings continue to ring and hum against the wood long after you’ve plucked them. Feel that vibration against your ribs. That is the sound of the islands staying open.
