People with Parkinson's often experience an ever-quieter speaking voice, difficulty with enunciation and with swallowing. 

There are two therapeutic singing / musical programs for PwP and their care partners: Tremble Clefs and AudAbility.  They’re so much fun, and have demonstrated benefits for voice, breathing and swallowing. And you don’t have to be able to carry a tune or read music!

Tremble Clefs, a 501(c)(3) organization, was created more than twenty years ago by Karen Hesley, who serves today as TC Board President.  They have chapters in San Diego, Encinitas, Rancho Bernardo, Orange County, Phoenix, and other communities nationwide. 

Tremble Clefs® San Diego is a fun and free, therapeutic singing program for people living with Parkinson’s and their care-giving partners and is generously supported by a community grant from the Parkinson’s Foundation. Under the guidance of a professional choral director, they sing popular songs along with active movement that provides singers with benefits that may relieve common symptoms of the disease.
