I really enjoyed going through this book, some of the pieces I still use for performing at local music festivals. The book takes you progressively through various musical stages and I found that the CD (purchased separately I think!) was also useful - it's good to hear what the songs are supposed to sound like!! You really feel like you have achieved something with even the most simple of pieces at the beginning, leading right up to the more complicated pieces toward the back of the book. The exercises and theory lessons are also pretty good.
I started out using a small harp (22 string) with this book, but a few songs require adaption or a bigger harp! This book is definately worth having even if you are fortunate enough to have regular tuition.
