I've been playing the tuba for a few years now, and bass for about a year. I find that playing one makes playing the other a lot easier. I know theory from the tuba and conventional band classes. That helps me compose songs for my band. Does anyone else out there play the tuba? Feel the way I do? I want to be a professional tuba player later in life. Tuba is my career plan and my passion, and bass is just a passion (maybe a side job) I am really good at tuba (or so I'm told) and getting good at bass. I hope they can both offer me a future.
