This is a terrific "method book for teaching/learning classical guitar technique. Since I purchased mine 53 years ago, the publisher has combined the first three volumes into a single publication, which is good in a way, but the new version doesn't lie flat on the music stand. Therefore, teachers and students alike must find a way to get around this problem! Another potential bu miinor issue is that technical tips for each exercise are written in Spanish. However, all fingering, positions, and accent marks are present, so, in my humble opinion, the author's comments, while interesting and insightful, are not essential in the hands of an experienced teacher. Apart from the book itself, I love the fact that Walmart is in 'music" business! For ancillary items like method books, guitar cases and "gig bags," Wamart's selection and prices are terrific.
