Jim “Kimo” West is the guitarist for “Weird Al” Yankovic. You may be surprised, or perhaps not, the music he personally creates is slack key guitar.
Per Jim’s website, “Hawaiian slack key guitar (ki ho’alu) is one of the great acoustic guitar traditions of the world, dating back to the 1840’s when guitars were first brought to Hawaii and relatively unknown outside the islands until recently. “Slack Key” means that some of the strings are slacked from standard tuning, with the bass, melody, and improvisation played at the same time, and is often played to accompany traditional dance or song. Many players use their own special tunings that often remain proprietary secrets.”
