This is one of my favorite books. Aside from including Giuliani's 120 Right-Hand Studies (extremely effective exercises) and Tarrega studies, Tenant has some really great studies on finger independance, developing the thumb, flamenco techniques, tremolo, control and velocity. I also liked what the author had to say about performance anxiety and practicing with a purpose. I can't believe how much great material is packed into fewer than 100 pages. Highly recommended.
