The West Side Tremble Clefs will present their first concert of the 2024-25 season 3 p.m. Sunday, Sept. 22, at the New Song United Methodist Church, 16303 W. Bell Road. The public is welcome to attend.

The Tremble Clefs are music groups for people with Parkinson’s disease, their family members and care givers, with no music experience required. Parkinson’s disease is a neurological disease that causes deterioration of muscles throughout the body including loss of voice. The purpose of the Tremble Clefs is to intervene the voice loss by improving voice volume and speech through singing and focused exercise.
