Silence is also a language, only if you can understand it. It is one of the purest languages you use to communicate with your god while praying. Humans rarely can read it. It is way too spiritual for humans to understand unless you know and love the person very deeply who is silent.
There is this Hindi song which is one of my favourites. Khamoshiyan! It is a lovely song.
Though I am not into songs and I don't listen to them much now, there was a time when I was in college and when I was into practice, songs used to work like coffee to us. To keep us going, they used to be best companions during late-night workouts and used to act like therapy to overcome the stress and failures and submission of design and architecture.
