Giving Voice is an arts in health organization (though they don't explicitly call it that) that provides an opportunity for people with dementia and their caregivers to sing in a chorus setting. With groups around the country (and world) -- check the Giving Voice Network for a full list -- they also invite you to expand their reach by creating your own group using their toolkit. As of 2025, their Rural Initiative is providing funding to start groups in rural Minnesota and Wisconsin.
