The internet website does not allow you to enlarge the picture . The front cover of the taylor book has swopped between simple and melodic . I used the picture sent by the bass teacher of an old book as a guide but as I couldn't enlarge the picture I ended up ordering 'simple rather than melodic . My husband has just now ordered the 'melodic ' one from you last night but it means my son doesn't have the correct book for his lesson and I have a useless book . My fault for not getting my son with better eyesight to double check but an ability to enlarge the pictures on screen would help with correct ordering.
