For many years, musicians in Nashville have used a system of numbers, rather than standard musical notation, in playing and singing and at recording sessions. Neil Matthews, Jr., one of the original members of Elvis Presley's back-up vocal quartet The Jordanaires, invented the system and also wrote this book, which teaches the whole system and also includes quotes, stories and photos of country and pop stars. The second edition features 12 songs to play: Beautiful Brown Eyes · Blue · Boot Scootin' Boogie · Crying in the Chapel · Green Green Grass of Home · He Stopped Loving Her Today · Heartbreak Hotel · (Hey, Won't You Play) Another Somebody Done Somebody Wrong Song · I Fall to Pieces · King of the Road · Make the World Go Away · Mammas Don't Let Your Babies Grow up to Be Cowboys.
