(Book). Ron Centola's Guitar Chord Pickin'Tionary is a 220-page miniature guitar chord book. The winner of the Summer 2011 NAMM Award for Best in Show (small item) has a patent-pending perfect binding that keeps the pages intact. The book is 2 inches x 1 3/8 inches x 1/2 inch. It can easily fit into your pocket and is small enough to take anywhere. This chord book makes for fun during those times when you find yourself using the same chord paths and need a new idea for chord structure. The book is small but the chord diagrams are easy to read. They are standard size chord diagrams: 2 inches in height x 1-1/4 inches wide. The book is packaged in an attractively designed display case with two free picks and free access to the e-book Playing Bar Chords by Ron Centola.
