The full-dress robes of a Doctor of Music at Cambridge.
The Doctor of Music degree (D.Mus., D.M., Mus.D. or Mus.Doc.) is a higher doctorate awarded on the basis of a substantial portfolio of compositions and/or scholarly publications on music. Like other higher doctorates, it is granted by universities in the United Kingdom, Ireland and some Commonwealth countries. Most universities restrict candidature to their own graduates or staff, which is a reversal of the practice in former times, when (unlike higher degrees in other faculties) candidates for the degree were not required to be a Master of Arts.
The Doctor of Music degree, a higher doctorate, should not be confused with the Doctor of Musical Arts D.M.A. degree, which is the standard (Ph.D.-level) doctorate in fields such as performance (including conducting) and musical composition. (However, at least one graduate program, at Indiana University, has been issuing the D.Mus. degree since 1953 for a curriculum that would otherwise lead to the D.M.A. degree.)
The D.Mus. is also distinct from the Doctor of Philosophy (PhD) degree in music, which is awarded in areas such as music history, music theory, and musicology.
