Tremble Clefs (TC) is a therapeutic singing group for individuals with Parkinson’s disease (PD), their caregivers, and family members. Founded in 1994 by a PD support group in Scottsdale, Arizona, TC was established after the group realized that singing could serve as a therapeutic tool to address speech and voice difficulties in individuals with PD, such as reduced volume and unclear enunciation. Since its inception, TC has continued to support PD communities across various locations, including the recent establishment of Iowa Tremble Clefs in October 2023. TC offers an evidence-based therapeutic singing program, helping participants improve speech and communication, socialization, and mental well-being, ultimately enhancing their overall quality of life.

SoundReach choir was one of West Music's initial programs offered by their first music therapist. Started in 1994, SoundReach is a choir for adults with intellectual/developmental disabilities.

The Oaknotes Choir is Oaknoll’s resident community choir. The choir consists of over 60 residents from all levels of care (health center, assisted living, and independent living). The Oaknotes perform three concerts per year, and they enjoy much support from the Oaknoll community. The choir believes that the sum is greater than its parts, and we are honored to share our music with all of you!

We are a therapeutic singing group for persons with Parkinson’s disease (PD). We meet once a week, both in person and virtually, throughout the year and perform annually at our PD Singing Festival in August. We have persons with PD and students from Dr. Stegemoller's lab that make up the group.
