The Master of Philosophy (MPhil) in Music at Yale University is not a standalone, direct-entry program but is conferred to graduate students in the Department of Music (Graduate School of Arts and Sciences) after completing all PhD coursework and examination requirements—excluding the dissertation. The MPhil recognizes advanced scholarship in fields such as Musicology, Music Theory, or Ethnomusicology, and marks a formal milestone towards the completion of the PhD. Students typically enter the PhD program directly and receive the MA and subsequently the MPhil as they progress; there is no external application for the MPhil itself. 来源： https://bulletin.yale.edu/bulletins/music/admission-procedures
