Slack-key guitar (kī hō'alu) is a Hawaiian fingerstyle tradition for steel‑string acoustic guitar distinguished by "slacked" open tunings, flowing treble melodies, and a steady alternating bass played by the thumb. It emphasizes ringing open strings, harmonics, and graceful vamps that frame vocal or instrumental melodies tied to Hawaiian poetry and place names. The result is a relaxed, singing guitar sound that can feel both intimate and spacious, often accompanying hula or standing alone as a solo art.
