Guitar

Normally six-stringed, a guitar is extremely easy to play and master, so most (if not all) guitar players are musically illiterate. Being unable to read notes on a five-line staff, guitar players instead invent tabulature, which basically shows exactly where to play the notes. 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.
