By now i've probably confused you all, so I apologize for that. Basically I've always liked playing something different, so in fourth grade I picked up viola, fifth grade tuba, and so on. Thanks to tuba I've discovered my new found passion in bass lines, so I got myself a nice little 5 string Ibanez. Well, I want to learn how to read sheet music and tab stuff. I have the tab learning going along nicely,,, and now I want to start with the sheet music. Well, here's the thing: I don't have that much money for bass sheet music things, but I do have tuba music EVERYWHERE. Hence, I was wondering if it's alright to do the standard 'find the note, know the name of the note, then find it on the fretboard' approach with it. I know where the tuba goes too low for my bass, so that parts alright, and I know how to find my lowest bass note on sheet music, just need more practice. So yeah, think that could work for me? Another thing,, I started out on Double bass so I got used to anchoring my thumb onto the fingerboard while I played. What I've been doing is finding little niches for my thumb and keeping it there, and it gives my fingers a lot more security. Thing is, I'm not sure if I'm aupposed to do that. Am I, and if not, can you describe proper posture for someone who fingers the notes? Thanks!
