Completely agree in both cases. I am not here to persuade anybody. But music is about sound, I think I wrote that to.
The matter is how do you write it down, with a sound structure underneath.
Children will need much time to pass in the grammatics. F key left hand, G Key right hand. And that is o ly the start.
Whether you write a note g on the second line right, and 1 line left hand, is already something strange for a beginner.
In klavar each note has the same position within the skeleton of the piano.
You can decrease the number of chords and keys for a violist, and just give him the part he needs.
Harmony from the beginning was there to underbuild the notation.
Nobody of course, certainly not those who spend 9 years in secondary education, to give it an applause.
I know the 2, and I say it does, because finally it's the sound that counts, not the piece of paper.
And I tell you that learning from memory having "understood" fhe "klavarharmony" will be a motoric memorisation, based on the keys on the score, a motoric process that the memory immediately translates into sound at the correct place.
It's not because you have a genuine grammatic, who needs lots of symbols to make it fit in the chromatic scale that you have a wonderful soundsystem.
Why wouldn't it be able to open doors for less talented musicians, but who have the passion. You don't use anymore letters, you use emails with lots of mistakes in it. That is a trap. Don't hurry in klavar because it is so easy to read.
Anyway there exist klavarplayerd entering amateur competitions.
Faure's nocturnes are no gimmy. They are beautifully layout in klavar.
But again. Whatever system you use, it's the SOUND that matters.
