I'm trying to go through the book "Building Walking Bass Lines" and am a little confused about something that's probably really basic but I don't think the book adequately explains. On the exercises where it gives the chords and only slashes on the staff, the first being a root notes exercise, I'm not clear on where to play the lower root note or the octave higher. Also on the fifths exercises, do you play the higher or lower fifth and which octave do you play before it? Is there a "correct" way to do this or is it kind of bassist descretion? I hope this isn't a stupid question but I feel like I could use a little hand holding here.
