It is worthy to note that people with no musical knowledge whatsoever can still play the music written by supposedly professional "artists", which says a lot about modern music. No random faggot would be able to play the works of Mozart or Beethoven.
Some versions of guitar even use electricity, these guitars sound even worse than their acoustic counterparts and even waste resources. In my opinion the people who made electric guitars deserve to be hanged.
Me: What note is that you just played?
Guitar player: Uh, I don't know.
Me: What key is the song in?
Guitar player: Wtf is a key?
Me: What's the time signature?
Guitar player: ...
Me: You call yourself a fucking musician?
