well i've been playing a year and a half, about a year with lessons once a week... and i still am having trouble playing with people, and listening by ear. Are there any books from www.amazon.com that are good for "begginers-intermediate"... I would like to learn to play by ear, play smoother, slap and tap better, learn bass lines... etc. I went on amazon.com and theres just too many good books, and i can spend 50.00's on books all together on bass... So can anyone tell me 2-3 books that meet my demands... or what i'm looking to learn?
