I'm assuming we are talking about Ed Friedland's book here.
can I make a suggestion? If you are not up to speed with reading standard bass clef, get Ed's bass method books (Hal Leonard pub.) and work through that first. I have the book that has vol. 1,2 &3 combined. Great for getting your reading and basic theory up to snuff. Also, Vol. 3 has some studies that will help lead you into his walking bass book. This is a fun well thought out book that makes learning these things EASY..... (with practice).. and the play along tracks are great/fun/enjoyable!
