The violin is considered to be one of the hardest instruments to play. Being able to play it means that you have put a lot of time, effort, and tears so that it can start producing beautiful sounds. It will be hard to play the violin without the bow because it will be hard for you to control the vibrato of the sounds that you want to play.
You are required to multi-task when you are playing the violin. You need to remember the chords that you are going to play plus you need to remember how you are going to use the bow back and forth. Bowing too hard may produce awful sounds and you do not want that.
