It seems like there are tons of books on jazz bass. It is easy to see why, what with the breadth of the subject. I own a book on reggae bass and one on country bass. But I don't own a single book on rock. It seems like there is very little in the way of respectable rock bass books. There are a number of play-along books that teach you a few songs and there are some really thin beginner books, e.g, Beginner to Pro type garbage. There is no Rock Theory book by Mark Levine. There is Ed Friedland's Building Rock Bass Lines, and it is not bad. But it struck me as a bit thin and basically more of a rewrite of his Walking bass book. Anyhow, I'm not inclined to dismiss the subject as self evident or simplistic. There is so much good rock out there that argues against that kind of close mindedness. So I thought I would ask the TB community if they had any rock bass idioms, revelations, or observations about rock bass. A lot of you have played rock bass. Some of you teach it. What are the things that you point to and say, "this is real common in rock" ???
