Would there be a way to grade or allow someone to orient themselves on multiple spectrums for different skills related to the instrument or music in general? Grading inherently isn't bad, it's the gradient on a spectrum - however the way the word has been used as all-or-nothing pass-fail with the perception that your future access to education riding on it is of course terrible. But I would like to be able to orient myself somehow and I can imagine some insights and direction could be gained by being able to input the output of your music/sound generated into a system could be useful, so long as the output isn't presented in a harmful way.
