I got this when the book was on sale because the premise matches my thoughts on the interconnectedness of language and music. This expands that topic and gives several concrete things a language learner can do to increase language effectiveness. It is a resource I have turned back to several times since my purchase when I want to find new creative outlets and ways to improve the overall sound of my language.
One caveat: I had purchased the pdf format of the book. It is diffcult to read this pdf on a computer because the spacing is off. Once I put that into an ebook reader, however, that problem no longer existed.
