Last updated on: 2009-08-19 2:26 PM

A minor/major ninth chord is composed using a root/1st, minor 3rd, perfect 5th, major 7th and major 9th (or R/1-Flat symbol3-5-7-9) intervals played simultaneously. Generally written as Cmi(MA9) or C-(maj9), it is good practice to simply use an uppercase C, the lowercase letters mi followed by superscripted uppercase (MA9) to represent it in writing (ie: Cmi(MA9)).

The tonality of a minor/major ninth chord is heavily dissonant and distinctly unresolved, as opposed to the stability of a major seventh chord.

Minor/Major Ninth Chord Voicings

The chord voicings below are not shown in any particular key, they are shapes which can be moved around the guitar neck freely using the root note (circled dot) as your navigator. See example below.

  • How to use
  • As an example, let's say you require a D major chord
  • After playing all the chord voicings, you decide on voicing #2
  • Voicing #2 has it's root on the 5th string so you need to find the D note on this string
  • Click the notes on the neck chart tab and find the D note on the 5th fret (5th string)
  • Now play D major using voicing #2 on the 5th fret
  • Use the Octave chart tab to help you remember which notes are where
  • Use the Chord chart help tab if your a beginner at reading chord boxes

Using octaves to learn notes on the guitar neck

  1. First determine which chord you require, let's use a B major chord in this example.
  2. We know the root note is B, (if it were an A major chord the root note would be A and for Cma7 it would be C, etc etc)
  3. Using the notes on the guitar neck chart, find the B note on the 6th string, 7th fret.
  4. Now using the major chord voicings chart, look for voicing #4 which has it's root note on the 6th string and play it, your done!
  5. Remember, learning and memorizing notes, chord voicings and scales in this way will improve your playing skills, theoretical knowledge and desirability as a band member.
