In this chapter, findings from previous chapters are reviewed, including a summary of kinds of experience that occur in music therapy. The differences between ‘outsider-measured linear evidence of therapist-set outcome’, and ‘insider-measured emergent evidence of therapeutic experience of personhood’ are highlighted, as is the importance of clarity in this regard. Cultures of music therapy are revisited and problematic cultures are identified. A final question is posed: ‘What would the field of music therapy need to be like, for those music therapy experiences that do not currently count as evidence to do so?’ In response to this, potential changes of approach within the field are suggested, including a greater emphasis from practitioners and researchers upon the arts-based phenomenon which lies at the heart of the music therapy encounter. Combined with an understanding of the author’s proposed ‘four phases of experience’, this could validate the other knowing that grows from music therapy, and the therapeutic experiences of personhood it affords. In keeping with the arts-based, experiential purpose of this book, this chapter is told by the four Roles who emerged as different aspects of the author’s voice, earlier in the enquiry.
