Music Theory For Guitar by Desi Serna. Scales, Chords, Progressions, Modes and More!

  • Guitar Theory should focus on applying music to the guitar fretboard, not other instruments (such as the piano) or a notation staff!
  • Pentatonic Scales and Major scale patterns, not the ridiculous exotic examples you see in scale books, are used to play melodies, riffs, lead guitar solos and bass lines!
  • The CAGED Guitar System is the secret to building chords, playing chord inversions and arpeggio patterns, not chord books with never ending pages of diagrams!
  • Guitar Chord Progressions are based on major scale chord construction, simple fretboard patterns and playing by numbers, not key signatures, sharps and flats!
  • Guitar Modes and modal scales are based on major scales, chord progressions and tonics, not new patterns or starting positions!
