Thanks! Yes certainly, the notation looks outdated. Even the names and terminology are so ingrained in western classical. Lately I've been using numbers 0-11 for the intervals, instead of the traditional 1-7 with a confusing system of #'s and b's. 0-11 uses more numbers, but at least I can just subtract two different notes to find the interval between them.
the intervals being important is one of the problems with its notation. But then we have Ornette and Andriessen and many others after them who write otherwise; free-er with emphasis on different elements or structural shapes. Obviously, the terminology depends on the composer, but in old classical music up to about 1960, that is true. After that, there was a lot of linguistic variation. The sharps flats thing is really confusing, especially to learners. Then there is the whole transposition thing. (on different instruments) And all of this because composers want to make sure their music will sound almost exactly the same each time it is played so we all know who to give credit to. The cool thing and the progressive thing would be to let go of that idea of attribution and reproduction being the key thing. It is very colonial, not very artistic, actually. In my view, we should always be reaching for something as artists, and the underlying philosophy has been revealed to be outdated- not aspirational for our world today, and rather elitist. It would be cool to have more people like you working on new notation systems that open up the field.
