I’m a musician who can’t read music notation and found it hard to pick up when I’ve tried. I assume I’m the target demographic for this system. At first glance I can’t for the life of me understand why I’d put the time into learning this. For one, it doesn’t appear to make anything that I personally struggle with any simpler. For two, the entire point of learning to read music is to communicate with other musicians. If I am writing my ideas in some bespoke system that no one else knows, what’s the point?
