Testimonials

A wealth of knowledge with the greatest ease of accessibility. Like a proper education, it leaves me eager to pursue the answers to my own questions through experimentation, rather than frustrated and scratching my head over the same unanswered questions I began the book with. I dislike this phrase because it feels like superficial consumerism, but this book is truly "Quality Content!"

Enjoy it!

Although I am far from finishing it, I can already say that it has been the best investment I have made into my musical knowledge. It contains all the information you need to start composing music in any genre that interests you. All of this information is provided to you in an easy-to-follow approach that anyone at any level can follow.

I see myself in the future coming back to this book.

Absolutely worth it! Very detailed and easy to follow. With many examples and song progressions to listen to and practice on your guitar.

So much work and love put into it, thank you!
