Example... Calculating E6/9
  • 6/9 chords consist of the 1st, 3rd, 5th, 6th and 9th notes of a Major Scale
  • E chords are built around the E major scale. We need to extend the scale to include 9 notes as we need to add the 9th note which is one octave above the 2nd note.
  • E major scale reads: E - F# - G# - A - B - C# - D# - E - F#
  • Formula for a 6/9 chord = 1 - 3 - 5 - 6 - 9
  • Substitute notes into the formula (1=E, 3=G#, 5=B, 6=C#, 9=F#)
  • The E6/9 chord reads: E - G# - B - C# - F#
