Minor 9th chords

The Minor 9th (m9) chord can has a kind of mystic and ambient sound. The most common shape is easy to memorize if you are familiar with the 9th Chord. The difference is that one note is lowered (on the 4th string), which results in a longer stretch. The 1st and 6th strings are marked with "x" (the 1st string can be played if you prefer to bar the three highest strings). If we compare C9 with Cm9 we could see that the notes changes from C, E, Bb, D to C, Eb, Bb, D.

Notice that the shapes are the same (notice also the irregularity for Bm9). This means that the chords are movable and, therefore, you can easily find out how to play C#m9 /Dbm9, D#m9 /Ebm9, F#m9 /Gbm9, G#m9 /Abm9 and A#m9 /Bbm9 as well.

The less common minor 6th/9th chord can be played with a similar shape, for example Em6/9 as X7567X.

The minor 9th chord can be found on the ii and vi degrees in a major scale. In C major, this would be Dm9 and Am9 whereas Em9 would be a non-diatonic chord because of the F# note.

In minor 9th chords, the 2nd and minor 3rd intervals (same as 9th and minor 3rd) will create a dissonance. But two tones that create dissonance played together can sound great harmonized in the full chord. For example, the notes D and Eb (that can be found in Cm9) will sound dissonant together, but not the Cm9 chord.

Bm9 - Amaj7 - Dmaj7

Dm9 - Am7 - Cmaj7

The minor 9th is well-suited in gypsy jazz and one possible progression is:

Em9 – Dm9 – C9
