So I just purchased a bass guitar a while ago. I played guitar and keys until four years ago, but wanted to get into it again, since music is a big part of my life. Don't want to dedicate so much time to it necessarily, so I'd rather become a good bassist than a crappy guitarist or crappy keyboardist. So... I have 4 strings on it. 21 frets, no inlays. I tuned it to B at this point (I Worship Chaos, Hypocrisy, Type O Negative and such...). I don't know how to get tux guitar (or guitar pro) working on my computer... I learned where the octaves go in relation to guitar and keyboard, it's fascinating. What should I practice? What should I learn? How do I practice my ear? It's very hard to tell the root note underneath the rhythm guitars and everything in music like COB. I plan to play mostly stuff like Hypocrisy, maybe some doom, as bass is not really the thing in COB's music. From what I understand the basic principle is to play the lowest notes of guitars but at the moment the drums hit. Open this up for me... Describe the path to learning to play songs without tabs.
