Book excerpt: Shapes and patterns are widely used in teaching the guitar, be it for scales, chords, or arpeggios. This book takes a novel and different approach to the guitar fretboard, emphasising an intervallic thought process. Moving away from shapes and patterns, this knowledge of intervals on the fretboard and its geometric properties leads to an intelligent choice of notes based on their harmonic function. Praised by guitar greats Brent Mason, Biréli Lagrène, Brett Garsed, as well as Jimmy Brown (Guitar World) and Prof. Richard Smith (USC), Intervallic Fretboard demonstrates the versatility of intervallic thinking in various music genres and playing styles.Accompanying CD/audio is available separately (see website).– www.intervallicfretboard.com –
