But talking technically Schoenberg's "Composition" book is good as far as I have read it , some books take music creating as a silly and easy task but Schoenberg sees it as a devoted artist should see music , it's not something that you can rely on "For Dummies" or etc...this is a serious job. and if you are a pirate you can use this link : http://thepiratebay.sx/torrent/4630039/Books_on_Music_Theory_(Harmony__Counterpoint__Orchestration)_[in This link contains a lot of good books in music and composition but you should be a pirate to use it! (it is illegal in some countries but not mine)

Life of Beethoven by Romain Roland Actually it is not about composition theory but it is about how an artist should be, it can help you with all of your later troubles in life
