The Recording Academy added the category Best Hawaiian Music Album to the folk music categories in 2005. Hawaiian music is famous for slack key guitars, these are guitars that are not tuned to the standard guitar tuning, and instead the keys are slackened till the six strings form a major chord, namely the G chord. Slack Key Guitars have been played only on acoustic guitars and Hawaii has been known to have kept the slack key guitar style a secret for a long time, and it was developed mainly by the islanders themselves. Daniel Ho has won the award every year since 2006.
