Didgeridoo for our Know Your Roos day? You know we had to do it. 🦘 The didgeridoo is an ancient wind instrument developed by Indigenous Australians of northern Australia. Classified as a wooden brass instrument, it consists of a long, hollowed-out tube that produces a continuous, resonant droning sound when the player vibrates their lips into the mouthpiece. #OAKvBHM | #KnowYourRoos
