What's Inside My Cello?

I have started training on the cello again and am so excited. We went to a cello concert last week where I will be training, and I was sitting so close to the cello I could feel the vibration. They did SUCH a good job. It was so awesome to get to see. I wondered, what is inside my cello?

All of these parts work together to make a super cool sound and a really fun instrument to play and listen to.
