Hi, Daniel
Really nice work on your website with regards to the subject of Music and Music notation.
I already expressed my concerns about the contradicting criteria of Music Notation Modernization Association, which also rendered my PMN system incompatible with the requirements.
But that is not really important.
It is promising that you think, "one of the hindrances of introducing a new notation system is that there is not a lot of work produced in a new system compared to existing ones. This is however something that software could potentially solve...".
I am hoping for that as well. That is why I fairly recently started to learn JavaScript. I will attempt at making some web-app to suit my PMN system.
If you happen to know someone skilful in this JS endeavour, please, let me know!
It will be almost impossible to confront that 800 years old beast called "standard music notation". But it is not impossible!
