Note that if you have done many of these more-focussed and privately-run dance, music or visual art based courses, this does not make you (as you would intuitively like to conclude) a creative arts therapist or an expressive arts therapist. In short, dance therapy + visual art therapy + music therapy ≠ expressive arts therapy. Expressive arts therapy is a whole other modality and is to be treated that way.
Seems all too wordy considering all this started with the main prerequisite being people with a strong intention of ‘healing’ through their respective medium or art form. Having said this, knowledge is power and this information does help us spread accurate, standardised and authentic awareness of what Arts for health and wellbeing is and what it is not!
