I've been singing for quite a few years. I took choir, private lessons, then did acapella and a sort of glee/karaoke group. I'm taking a break from it now. I love it but I've always been a terrible singer.
I've also been playing cello for a while now (I can't keep track of time) and I enjoy playing a little bit of classical but also rock and pop on it.
I've strummed guitars, pianos, and violins but never really given them much of a go. Cello is the instrument that clicks with me the most.
I would love to be able to play a multitude of instruments, but I'm extremely happy with cello. So, I guess the only thing I would wish for is an electric cello. Those things are awesome; I love playing them! (And super expensive).
