9. The Trumpet
If there were more people like Louis Armstrong, the trumpet wouldn’t be on our list of the most annoying and hated musical instruments in the world. Unfortunately, playing the trumpet is not a piece of cake. Hours of practice and lip buzzing can easily drive you mad. Not to mention the collateral damage – the poor family and edgy neighbors. Although it’s loud and sometimes obnoxious while played at home, the trumpet sounds great in classical and jazz ensembles. So, if you are a trumpet player and you love your instrument, practice in the place where you won’t be bothering others.
