CAMDEN — Instrument creator and sound therapist Jim Doble invites the public to bring a chair, blanket, or yoga mat to relax upon as they listen to the transformative sounds of his resonant instruments.

The event is scheduled for 4:30 p.m. Friday, Oct. 15, at the Camden Amphitheatre on Atlantic Avenue.

Doble will be joined by Forest Weston, who will play a variety of didgeridoos.

During outdoor group “sound baths,” Doble uses mostly gongs, along with an assortment of singing bowls, tuning forks, and instruments that he’s created. Doble also appreciates that the amphitheatre is a place “where the sound of birds and the light rustling of the sea breeze through the trees adds to the sonic ambience,” according to a news release from the Camden Public Library.

The event is by optional donation. A portion of donations will benefit the library.

The library encourages registering with Doble ahead of attending so that attendees can be notified if the program is canceled. He can be contacted at [email protected] or 207-785-2212.

Doble has collected and made a variety of large gongs and other instruments for use in both his private sound therapy practice, as well as playing for group sound baths.
