Hal Leonard Ron Carter Building Jazz Bass

As a professional Classical bass player I bought the book to start learning on how to build good walking basslines. There is the main principle explained and for begginer it is OK. Though I could not find any further directions and explanations or ideas about how the bassline should be expanded. Also there were no theory explanations, which might leave a student a bit lost If looking for a reason of a certain decisions made in the bassline. I would recommend this book for begginers theory and technically wise.
