Edition Dux Congabuch

Pros -
I already play congas but my weak point is the notation, so I decided to try this book to improve my reading and so I could also teach others to play congas and this book is ideal if you want to strength or review your conga playing as well as if you want to use it as reference to teach others.
Is one of those books where the pages are attached to a metal spiral, so it makes it very confortable to keep it open and read it while you play.
The book comes in German language, I dont speak German but it is quiet simple to understand, maybe it is just a few words to translate via internet and you will understand it all.
Cons -
No English.
