Oh, this book is a fun read. It's short, but fun. It is for anyone interested in Flamenco and how it evolved, more than just tourists, teachers, and students the title implies.
It's chock full of information by an enthusiast of the art form and Spanish teacher for a couple decades. (More about Rachel Kirk.)
Here is a book description by the author: This short e-book includes a thorough yet concise introduction to the Spanish art that includes song, dance, and guitar. It informs the reader about the origins and evolution of the art in Andalucía, and about each of the three elements of flamenco. Readers learn what to expect at a flamenco show, as well as what to look and listen for in order to more fully appreciate the performers on stage and the art of flamenco itself.
I had originally intended to include only one of Rachel Kirk's books, because you'll be able to find the rest of her books when you get to Amazon. But her response to my query about this particular title made me decide to include it.
Here is her response about why you might want this book:
"50 Keys" is hot off the press. It is mainly for students who get behind in their Spanish class and/or need additional help, but it's also great for students in the growing number of states where there is just a "classroom set" of textbooks, which means students are not allowed to take their textbooks home. In other words, it is for people who are studying Spanish and need a resource that explains the concepts. So if you think your readers or their kids would find it helpful, it might be a nice option.
