Yep. It's fabulous.  I think you can get it at his site or Amazon...  And....he has a book (same title) with the complete notations and tab for each piece.   They vary in difficulty, but can be learned, although painstaking.  What I find really helpful, is by studying just a few of them, it opens up this vast highway of possibilities with the altered tunings, and then you start composing different sounds on your own, that I don't think would be possible without his instruction. 

And..if you really wanna get into it, he has these mini-residencies at his nice farm house in France...I'd love to go sometime.  He is such a wonderful guy, and absorbing his philosophies is more than enough even if one were to never play a note.   INTUITE.
