Hawai'ian Slack Key Guitar

Slack-key guitar is a finger picking genre of guitar music that originated in Hawai'i. Its name refers to its characteristic tuning: the English term is a translation of the Hawaiian ki hoalu, which means "loosen the [tuning] key". Most slack-key tunings can be achieved by starting with a classically-tuned guitar and detuning or "slacking" one or more of the strings until the six strings form a single chord, frequently G major.

In the oral-history account, the style originated from Mexican cowboys in the late 19th century. These paniolo (a Hawaiianization of españoles—"Spaniards") gave Hawaiians the guitars and taught them the rudiments of playing, and then left, allowing the Hawaiians to develop the style on their own. (Musicologists and historians suggest that the story is more complicated,  but this is the version that is most often offered by Hawaiian musicians.) Slack key guitar adapted to accompany the rhythms of Hawaiian dancing and the harmonic structures of HAwaiian music. The style of Hawaiian music that was promoted as a matter of national pride under the reign of King David Kalakaua in the late 19th century combined rhythms from traditional dance meters with imported European forms (for example, military marches), and drew its melodies from chant (mele and oli), hula, Christian hymns (himeni), and the popular music brought in by the various peoples who came to the Islands: English-speaking North Americans, Mexicans, Portuguese, Filipinos, Puerto Ricans, Tahitians, and Samoans.

The music did not receive a mainland audience during the Hawaiian music craze of the early 20th century, during which Hawaiian music came to be identified outside of Islands with the steel guitar and the ukulele. Slack key remained private and family entertainment, and it was not even recorded until 1946-47, when Gabby Pahinui cut a series of records that brought the tradition into public view. During the 1960s and particularly during the Hawai'ian Cultural Renaissance of the 1970s, slack key experienced a surge in popularity and came to be seen as one of the most genuine expressions of Hawaiian spirit, principally thanks to Gabby Pahinui, Leonard Kwan, Sonny Chillingworth, Raymond Kane, and the more modern styles of younger-generation players such as Keola Beamer, his brother Kapono Beamer, Peter Moon and Haunani Apolonia.

Many currently prominent Hawai'i-based players got their starts during the Cultural Renaissance years: Cindy Combs, Ledward Kaapana, George Kahumoku, Jr., his brother Moses Kahumoku, Dennis Kamakahi, Ozzie Kotani, three Pahinui brothers ([Bla, Cyril, and Martin), and Owana Salazar. These artists, and slack key in general, have become well-known outside of Hawai'i largely through George Winston's Dancing Cat Records record label, which has most often showcased the music in solo settings.

One indication of slack key's increasing visibility beyond the Islands is that when The Recording Academy instituted a GRAMMY Award for Best Hawaiian Music Album, the first three winners were slack key collections produced in Hawai'i: Slack Key Guitar, Volume 2 in 2005, Masters of Hawaiian Slack Key Guitar, Volume 1 in 2006, and Legends of Hawaiian Slack Key Guitar—Live from Maui. Players from outside Hawai'i have also taken up the tradition, for example, Chet Atkins (who included slack key pieces on two of his albums), Yuki Yamauchi (a student of Ray Kane's and advocate of Hawaiian music in Japan), and Canadian Jim "Kimo" West (perhaps better known as guitarist with "Weird Al" Yankovic).
