1、Rootless Voicings

1)Major and minor chords contain the 3, 5, 7 and 9(or 3, 5, 6, 9 if on the tonic chord)

2)Dominant chords contain the 3, 7, 9 and 13

2、Chord Voicing Conventions

1)Do not play the 11th when playing a Major or Dominant 13 voicing

2)Sharpen the 11th when playing a Major or Dominant 11 Chord. The natural 11th can be played over a minor chord.
