The book is available at Just Having Fun Music in Burlington, and at George Breber Music in Elkhorn. Rathmann and Crimmins negotiated with distributors and several major music retailers and are selling to retailers in the Midwest through trade shows and other means. There are a lot of thick, encyclopedia books of guitar scales and chords. There are also 'method' books of guitar theory and instruction. But there has really never been a book describing exactly how a guitarist should go about practicing scales and arpeggios to build strength, flexibility and soloing prowess.
Every musician is supposed to practice scales and arpeggios.
That connection has a physical aspect, which is the key element in the book. Several fingerings of the major scales starting from the sixth, fifth and fourth strings are listed in the book. These lock together into patterns up and down the neck, allowing guitarists to quickly create fluid and expressive solos in the various modes of the major scale. The guitarist who uses this method should learn to create phrases by going smoothly up the neck. They may have learned it from other players.
