Slack key guitar

Slack-key guitar is a fingerstyle genre of guitar music that originated in Hawaii. Its name refers to its characteristic open tunings: the English term is a translation of the Hawaiian kī hōʻalu, which means "loosen the [tuning] key". Most slack-key tunings can be achieved by starting with a guitar in standard tuning 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") provided guitars, taught the Hawaiians 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 Kalākaua 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 (hīmeni), 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 develop a mainland audience during the Hawaiian music craze of the early 20th century, during which Hawaiian music came to be identified outside 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 Hawaiian 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, Atta Isaacs, Leonard Kwan, Sonny Chillingworth, Raymond Kāne, and the more modern styles of younger players such as Keola Beamer, his brother Kapono Beamer, Peter Moon, and Haunani Apoliona. During this period, luthiers such as the Guitar and Lute Workshop in Honolulu specialized in the development and manufacture of guitars custom made to order for slack-key performance.
