It is useful to know how what you like works. Any art becomes much more interesting if you are aware of how its works work from the inside. By replacing foolish contemplation with exploration, we, in general, become smarter. And if earlier it took too much to study the arts, now just a computer with a couple of accessories is enough – and now you are ready to do something with your own hands. For example, master the basic skills of composing music, which then maybe someone wants to listen to. Or buy.
