This book/Cd package covers the rock/blues harp subject well. It uses "stories" about cartoon characters to explain some of the concepts. Although you do need to do as JON says and have the harp in your hands and mouth as you listen to the CD. The key is to try each single note/chord out at the same time as he tells you. You really need to "jam along" right from the begining. At first, I thought the cross reference to the CD was not as clear as I would have liked - but this only seems the case if you don't "play along" as told. The book covers things in a progressive way, but the CD seems to go at a different pace. At first this caused me some problems but I was expecting a page by page correspondance with the CD. You need to skip from the book to the Cd and back again. Once I took this approach the real value of the package became evident. Over all an excellent tutor which brings good results very quickly with even modest practise.
