Some other fun examples of points in the music notation space are the various notation systems used by traditional Japanese musical instruments... For instance, the shakuhachi (a type of bamboo flute) has a system where various combinations of fingerings/blowing technique are each assigned distinct characters (the same pitch, but achieved with different fingerings, and therefore having different tone colors, will have different characters). Rhythm and ornamentation are then indicated with various annotations on these characters. You could maybe make the analogy that Japanese music notation relates to Western classical notation in a similar way to how Chinese characters compare to alphabetical systems...

Other instruments have similar (but generally mutually unintelligible!) systems, with different characters assigned to particular notes/techniques peculiar to those instruments.
