UKAN SIGVA have funded a video from the Acoustics Research Unit (ARU) at the University of Liverpool who provided vibrotactile equipment to the Royal School for the Deaf Derby to aid music education. See https://stream.liv.ac.uk/2qvwd9th. A part-time music teacher helped the ARU gain access to the school and the permanent music teacher did a great job of adapting the equipment into his teaching. This was the first time it was really feasible to teach pitch to the children. Obervations indicated that there are likely to be generations of deaf children who have misunderstood pitch. In this group of deaf children many initially thought that a high level of sound or vibration equated to a high pitch.
