Example: Calculating a Gm9 chord
  • m9 Chords consist of the 1st,♭3rd, 5th ♭7th and 9th notes of the Major Scale
  • 'G' chords, are based on the scale of G major which has 1 sharp (F#). The scale reads as follows: G - A - B - C - D - E - F# - G
  • As we are looking at a 9th chord, we have to extend the scale for an extra tone (2 semitones) The scale reads as follows: G - A - B - C - D - E - F# - G - A
  • Formula: 1 - ♭3 - 5 - ♭7- 9
  • Substitute the notes of the scale into the formula: 1=G / ♭3=♭B / 5=D / ♭7=F / 9=A
  • Gm9 reads as follows: G - B♭- D - F - A

Please Note

There are a variety of options available when playing these chords. Within each chord position where you have several circles with the same finger positions on the same fret, you can play this as a barre with the first finger, or you can choose to play some of them which can be useful if you are just picking a few notes. If you do omit some of the blue dots on these particular frets, make sure you avoid playing the strings, as they are not within the chord structure.
