I always wondered why musicians keep up with the conventional musical notation system, and haven't come up with something better (maybe a job for a HNer?). I mean the conventional music notation represents tones in five lines, each capable of holding a "note" (is that the right word?) on a line, as well as in between lines, possibly pitched down and up, resp., by B's and sharps (depending on the tune etc.).

Generally it can be said that some have been better in a specific use case (klavar notation was pretty big in the Netherlands among those who didn't know regular notation), but they fall apart pretty quickly when you try to write Liszt or Rachmaninov in it.
I might be a bit rigid (I have played bassoon professionally for most of my adult life), but I can't really see how it can be made much better and still keep the same utility.
While chords might be not optimal today, we can still express things like enharmonics easily (which, at least for me, is something that can make sight reading easier as it allows for the notes to stay "in key").
As with the spoken word, music has an advanced coding system. Both coding systems are flawed in their own way (as someone with a different mother tongue than english, I have a hard time spelling just about anything), but they have also stood the trial of time.
