Fretboard Theory Volume II: Guitar Scales, Chords, Progressions, Modes, and More by Desi Serna

Book two in the Fretboard Theory series picks up where the first volume left off and takes your guitar playing and musical knowledge to a whole new level. You learn many advanced applications and new musical concepts. There is information for rhythm guitarists, lead guitarists, improvisers and composers. Each chapter focuses on applications found in popular music and includes familiar song references. Gain new perspective on keys and tonalities. Apply new number systems. Bring dominant function and voice leading into play.

Change keys, borrow chords and mix modes. Employ chromatic passing, diminished and augmented chords. Use the lead patterns preferred by the pros. Target chord tones and outline chord progressions. Discover the harmonic minor scale. Play pedal point and pedal tones.
If you have passed the beginning stages of guitar, specifically if you know how to play the core chords already and know your Fretboard, then this book combined with the first book will take you from intermediate to expert. You will go from the world of riffs and licks to full songs. You will master the Pentatonic scale along with barre chords. When finished with both books you will not only be able to play but understand the underlying reasons for doing what you are doing.
