I'm 14 and I barley got my bass 6 months ago and I unfortunately started poorly (I wasted 5 months playing songs from tabs).I'm learning theory on my own (I know the notes,I just don't know any scales like Ionian etc). What books can I buy? I'm too poor to afford lessons (I did get 160 dollars total for christmas luckily,but that won't do) and if I did have the money,I don't have any teachers near by (only Guitar Center). I'm in marching band at school so I do know a few of the basics (rests,coda's,D.C al fine etc). The 2 books I have are The Bass Grimoire Hal Leonard Bass Method Books 1,2,3. I want to learn more and I want to get better.I use both fingers and picks....I want to get better and hopefully I can someday form my own band lol .
