I have been playing bass for almost exactly two years, and am having lots of fun with it! Playing covers in a band.
I don't have much trouble learning the sort of covers we play in the band as they're very formulaic, mainly being verse, chorus, repeat a couple of times and add a bridge in somewhere. But for more complicated stuff I find it difficult if not impossible - mainly because I have ADD, and my attention span wanders either on to a different song, or somewhere else completely.
I've been trying to learn Battery and The Four Horsemen (Metallica) for about a year now and although I can learn the main riffs easily enough, there are long crazy bits that are not repetitive (like the bit under the solo in Four Horsemen) and I just can't keep at it for long enough at a time to figure it out.
Practicing and theory are even worse. I'm lucky if I can focus for long enough to remember to pick my bass up and play it, but there's no structure, I'm just banging out a few riffs. I've tried to add structure to my practice sessions before, but wandered away from that as well. And I have tried to learn theory, had lessons a couple of times, etc and... well you know where that's going.
This is frustrating as hell! I feel like I could be fairly good if I could get stuck in but it just seems impossible sometimes. I'm sure it's not, I just need some guidance
Anyone have any similar experiences, advice or suggestions?
