“Singing for the brain” attracted 20 people for its first session and meets for the third time on Wednesday.
Organisers said Alzheimer sufferers will often remember all of the words to an old song, even if they cannot hold a conversation.
They said singing was empowering and was helping people with the brain condition.
Dementia is the gradual loss of brain function leading to loss of memory and the inability for patients to understand what is happening around them. It affects 800,000 people in the UK.
