One of my grandsons is playing cello. He’s five.
It’s gotto be bigger than he is, unless he is lucky enough to have a model sized for a child! My father’s twin sister played the cello, along with many other instruments.
My father was from a family of 9, raised on a ranch in CA. My grandmother had been a music missionary to the Choctaw tribe in Oklahoma Territory before she was married. So, she taught all of her own children different instruments. She wanted her children to be able to have an orchestra to entertain them in the evening.
All of the girls (my aunts) eventually taught music, but my dad never did anything with it. He would play the first page of The Swan beautifully and then claim that he didn’t feel like playing any more. My mother was married to him a year before she learned that he didn’t know how to play the piano at all. His sister had taught him one page and stopped.
His assigned instrument was the cornet, and he didn’t like it.
