Hey Todd, I was wondering which books/DVD's cover your horizontal approach to scales. I play a 5-string bass tuned E-A-D-G-C. Thank you for your time. Edit: I imagine all your books and DVD's are worthwhile, but if you were to recommend one of your teachings, what would it be, I am 49 yrs old and i have been studying theory and jazz for the last couple years, I studied a year at City College(New York). I recently took a lesson with a very good player that felt I am boxed in by my across the strings vertical approach and that if I played in a more horizontal method, my playing would open up and be more creative, so he suggested I practice scales, heads, and melodies this way. I searched on Talkbass and found a thread with you discussing something similar. Any thoughts? I appreciate any input that you have, I have tremendous respect for your knowledge and of course your playing.
