Yes, all three of us. Bianca asked for a cello for her birthday and begged to learn cello this year in beginner orchestra (of course she will still be playing viola in advanced orchestra too). So I found a cello on KSL classifieds, and we picked it up about a month ago. That's when Bianca started showing me where the different notes were. She said she just watched last year when the orchestra instructor was showing the cello students. The only cello music in the house was the stuff Bianca had written, so I picked out a couple easy songs. Yes, I know I'm too old for something like this and much too big for this 1/4-size cello and it's ridiculous I'm trying to play an instrument I never even touched my entire life, but it's kind of fun. I also realize how horrible I am, but I'm learning. I'm so proud of the calluses on the pads of my fingers on my left hand I got from playing. Portia likes to have her "cello lessons" every day too and we have to put the end-pin down as far as it will go (mine has to be up as high as it will go) and she just bows back and forth.
I've been practicing a song Bianca wrote especially for me on the cello (to play with her on viola) called "Cello in Vienna."
