I would beg to disagree with you. Many attempts have been made to replace music notation as we know it, and all have failed. In fact, more cultures around the world are adopting "western" music notation than ever before. It turns out that the expressiveness and information density of the notation are hard to match with any other system. In turn, the notation that we use has become more flexible than ever. There are rich notations for microtonal music, various playing techniques, clusters of notes, and many more things. If you took a score by a modern composer (see Saad Haddad's pieces on YouTube) and showed it to JS Bach, it would be unrecognizable to him. Music notation is a living language just like English is. By the way, I have been an on-and-off professional in the music world, although it is a "side gig" to programming, including some composing, tuning, and playing. However, it is undeniable that music notation is a system made for power users. It's not an easy language to learn. The ideas of "information dense" and "expressive" should remind you of the ideas behind the A programming language.
