The Cactus Key is a prickly instrument that’s surprisingly fun. German musician and developer Markus Lindemann wondered if a cactus would change its tuning as it ages. So he picked one up a cactus and discovered that the spines have a B-chromatic scale.
Lindemann dubbed his unusual instrument the Cactus Key which makes us look at the plant in a whole new way. Check out the video to watch the Cactus Key being demonstrated.
