Festival Founder and Director Bill Becker said music in water travels five times faster than in air, making it feel very interesting.

“Now in air you can generally tell a direction sound is coming from but when it travels so fast it arrives at both of your ears at about the same time so you can’t tell any direction so it sounds like the music is all around you. You’re not only just hearing it through your ears, you’re hearing it through your head and your jaw and your entire body. You can actually feel the music,” he said.

The Underwater Music Festival also carries a serious message of reef preservation. The broadcast incorporates diver public service announcements emphasizing ways to enjoy coral reefs while minimizing impacts on the underwater environment.

Divers and snorkelers can reserve space on boats or launch their own boats from public ramps and marinas in the area around Big Pine Key. The Underwater Music Fest is from 10 a.m. to 2 p.m. on Saturday.
