I was thinking about humans- and any other objects resonating.
I myself have played classical violin for the last nine years. And just few years ago after I stopped growing, I’ve noticed that my body resonates when hearing lower sounds. Like low c- played on bigger stringed instruments like cellos or contrabasses. Sometimes in concerts I feel my whole spine and lungs resonating with one particular sound. Same with my violin.
I’ve looked it up and tested it with friends and adults. It’s not the same for them which I find rather weird. I even asked my teacher about it. She tried it and said it’s a funny thing. Her violin doesn’t start resonating with the same chord. What could be the cause of it?
