Music is a way of representing the patterns of frequencies and vibrational relationships--and at St. Francis de Sales School for the Deaf, it is used it to promote language learning and transform students' educational experiences. Traditionally defined through the medium of sound, music has been seen as an approach that excludes deaf and hard of hearing people. By expanding the perception of music, the school has provided a transformative instructional experience for deaf and hard of hearing students with disabilities, allowing them to learn and grow in the music classroom.
