All Those Musical Symbols...
There are many note symbols used when writing music.
Music is so subjective and has so many means of expression that trying to write exactly how music should be played makes the use of many different symbols a necessity.

You might even find it fascinating, as I do, with the clever way that people have developed a system to “describe” something as abstract as music!
