The main challenge lies in helping someone articulate their own emotions, feelings, and musical intentions. Personally, I find this difficult to achieve on my own. Structured dimensions can certainly support a music project, but they may lack effectiveness if there is no clear understanding of the intended objective from the outset.
Nice project! Thanks for sharing. I would say that a robust qualification process may constitutes the primary added value of your project. Much like a sales representative who can methodically understand a prospect’s needs, it may be worth helping users clarify their internal feelings first.
Exploring how other scientific or artistic disciplines address this challenge could also be valuable.
