Music therapist is an emerging profession that emerged in Europe and the United States in the middle of the last century. The profession began to be introduced to China in the 1980s. However, in those early years, music therapy was only an emerging discipline and an emerging research field. It is known to some researchers in related fields, but there are not many music therapy workers who are actually professional professionals.
