I bet upright would be fun. I admit it's a little intimidating. There's no frets, and it's so big. There's actually a number of instruments that look like fun. If time, money, and storage space were no object I'd probably be a one man band. But sometimes I feel like a wanna be. I spent more years on the drum set. I was told my technique, coordination, independence and everything else is good. I just had to learn how to play. It seems I'm more of a technician.
