(Mandolin). Mastering the mandolin neck can be a challenge, even for very experienced players. The diagrams in this full-color book will help you quickly memorize scales and chords that may have previously seemed difficult to grasp. You'll be able to easily see and understand how scale and chord shapes are laid out and how they connect and overlap across the neck. The material is presented in all 12 keys, using complete 12-fret neck diagrams with color-coded displays of the most common fingerings.
