Music is a strange old thing. Once upon a time, some cavemen started banging on things and decided it sounded good, and now a huge chunk of human art is dedicated to being able to put a collection of sounds together in an order that makes people want to listen to it on repeat.
This whole practice of making pretty noises is such a phenomenon that we've invented a whole genre of things just to play them on. There are over 1,500 different types of musical instruments in the world, and each of them bring something unique to the table when it comes to the deal of song writing.
However, "unique" doesn't always translate into something that is particularly nice to listen to. Musical tastes are dependent on a lot of different factors and can vary wildly. On top of that, there's plenty of experimenting that people like to do with sound. This has led to some of the beautiful abominations below. It would definitely be interesting to find out what some of these sound like.
