Yes, exactly!
I there is no sound no music what would be the world at that time. I personally feel that when I bit sad and losing hope. I gonna sing a song and record it as well :P. Music will release your frustration and sadness will give you boost back energy with a new hope and idea. Sometimes I feel that when we listening to music its lyrics explain the current situation of life!

I like the concept of your warm light effect on the instrument even there is not warmth great effect to bring that kind of concepts awesome!
