My first experience as a caller was in January of 1981. I was teaching music at a psychiatric hospital and decided to add a bit of dancing to my teaching. I spent one night a week teaching on a ward for the hearing impaired. We placed the speakers facing the floor to help the sound be felt. Each student had one of our teaching assistants as a partner. This combination of transmitting the vibrations and having a partner who could hear worked very well. I've since found that using a demonstration set also helps those with handicaps to understand the movements. John B. Freeman, SFTPOCTJ
