- Aguado's method for guitar has been known to guitarists for many years as the best method available for students. And as well as being highly practical today, it is also a text of the first importance in the history of the modern guitar. Here is a new and fully professional English translation of his famouse work, with a new introduction and notes by Brian Jeffrey. The book is recomended as a practical method for the guitar; as a historical text; and as a reliable edition of Aguado's many studies, exercises, and other music, included here and edited for modern performance with the composer's own fingering.
