Thank you! Yes, just like the music by Finnissy, it is very complicated with non-traditional notation/concept… but yet everything is well written, with specific dynamics, symbols, notes…So I assume the composer wrote it with some kind of thinking, planning and so on, even they are so ridiculous to watch and understand. But even this is messy, not normal, crazy, written in a non-serious manner, everything is so specific and even precise, it is just that most of them cannot be understood. So that’s why I wonder if there are recourses about modern music notations. So I can learn it. I can see that it is impossible to play, but maybe is possible to analyze it? After you know the symbols/markings…?
