Very well said!

I put this note because I really all inclusive! Well of course I'm no novice in music, I have already more than 5 years of guitar under my belt but all without theory! I was missing something to really develop myself in music.
It took one month to finish the set by making every day at least above 1:30. After you start to have headaches
This book also includes a CD, I copied the content (audio sound) on my phone to read when I was without necessarily being in front of a computer. These sounds brings a real plus!
I recommend this book mainly for musicians with several years of experience without theory and want to learn quickly and well! But I think that if someone who has never touched instruments of his life wants to learn, he will have a little trouble because you need a piano or a guitar for the same work, so it takes some mastery !
