I would bet that your clever "genz/genalpha/ gen++" would be more likely to introduce better teaching system than establish replacement for musical notation.

Well I hope than someone does.

Apart from that, I get your points, and these are valid arguments. I appreciate them, my original post had no intent of offending peoples or calling names.

Although I don't find that the notation (with the perfectly added timings) simplifies the whole 'playing instruments' thing. Said classical notation becomes crazy complex spiderweb of pause and notes when you add legatos, syncopation, triplets, arpegiation, etc. It is not as universal also, as you claim - the guitar players don't prefer tabs (barre/fret) notations; drummers use rhythm charts more often, than never.

I can agree certain instruments (such as claviers and alike) may benefit greatly from this notation, which was created for them precisely. But I totally disagree this is universally useful one, and yes - I've tried it, has a very steep learning curve, and I'm very good at telling notes apart by only hearing them. The notation stays in the way of performance for me personally.

Call me dumb if u want, but my gut feeling is my position aligns with the vast majority of modern, non-classical musicians.
