The Sound Tree is an interactive sound and light installation conceptualised and constructed by myself and Amanda Brayham. Based on colour and sound therapy principles, our tree intends to indicate when a person is operating within stressful levels of noise or potentially irritating or unsettling frequencies, and invites them to move away from these negative influences and bring peace into their environment. When peace is found, the tree will glow colours that are proven to be the most therapeutic, and thus, the person or audience know they are in a safe place – a happy place – where they can relax and know no harm will come to them.
