Composing is a key element of music, whether you actually want to take that career path or not. Composing is basically like the for-ground for music because it’s creating the music itself. Composers such as Max Richter, Nils Frahm and Ludavico have created groundbreaking revolutions from their composures that have influenced music today.
Composing is also incredibly important because the musical underscore of a picture or a video can change your whole perception on it! For example, if you have a picture of a puppy sleeping but with a melancholy underscore, people will automatically assume the video is for sad purposes, like the death of the puppy or something. However, if there is a relaxing piano underneath then people will just think that the puppy is cute and it looks so peaceful.
