Hi Jamie.
loads of good advice already here. However, from a beginners point of veiw i thought i would add my pennys' worth.
I have been teaching myself for about a year now. I am lucky because i can read music, although i am able to read treble clef. I am very slow reading bass clef. I would like to learn to read it better. I have taught myself about 30 or so songs ranging from dire straights to muse to coldplay etc. Mostly stuff that i like and own on CD etc, and i have singled oout the ones that i feel have the easier bass lines. I have tried to teach myself 'its my life' by talk talk but just cannot get the 2nd bit where it starts to leap about a bit, even if i slow my tascam right down.
Id like my technique to be a bit better, and i worry that my left hand is learning too many bad habits.
I warm up with a few finger lessons taht i got off the internet from Dave Marks. I am also working my way through the Guy Pratt bass tutor on line, plus i have bass guitar for dummies etc.
So this is a picture of someone with a very small amount of knowledge. I am also looking for a tutor right now. I dont know enough about the tutors in my area, andam on a recce as we speak.
I hope it hleps from looking at the other end of the scale, I am sure I am not the only one like this that you may come across.
Musically, i am open to idea of what i want to be able to play. I certainly am not going to be another jaco, but i wouldn't mind learning some 'classic' bass lines and how to make some up, ie patterns and the like..( i think thats what i mean)
I hope that helps.
Good luck
Matt
