Understanding Extended Chord Construction
C9 (Dominant 9th) Example
- • Root: C (1st degree)
- • Major 3rd: E (3rd degree)
- • Perfect 5th: G (5th degree)
- • Minor 7th: Bb (7th degree)
- • Major 9th: D (9th degree)
Interval Stacking
- • 9th = Octave + 2nd (compound interval):
- • 11th = Octave + 4th (compound interval):
- • 13th = Octave + 6th (compound interval):
- • Guitar: Usually omit some notes
- • Voice leading: Choose most important tones
Practical Voicings
- • Guitar has 6 strings: Omit notes as needed
- • Common omissions: 5th, root (if bass plays it)
- • Shell voicings: 3rd, 7th, plus extension
- • Drop 2 voicings: Practical guitar shapes
- • Rootless voicings: Assume bass covers root
