I think you are proving the authors point quite well. Composing music to be performed if very different than sharing the composition of it with many composers.

I think you are proving the authors point quite well. Composing music to be performed if very different than sharing the composition of it with many composers. There is meter and scale and notation but only so many ways you can express things with the most complex being complicated meter. Now performing that - yes - more complexity but not in the composition. We dont need programmers to "perform" in every CRUD app on the internet. We arent all writing game engines, gpu drivers, etc etc. There are Beethovens out there doing things that require phenomenal skills (that can be learned) but its not 1:1 with composing music with performers limits in mind when the composer didnt HAVE to collaborate.
