My next door neighbor is 9 years old (I think she is 9... if not she will correct me) and has just started cello lessons. Tonight we had a very nice visit. She showed me her new 1/2 size cello, and all the songs she can play with A and D. Also, F#, a note she learned from another neighbor who is a year ahead of her. I showed her all the A's you can play on the A string. She showed me how to make sirens, and how to do a cello bow strum on the open strings. I showed her how great a cello bow strum with chords sounds. How cool is that?
