Cmin9

c-9

The Cmin9 chord (also known as C minor 9 and C-9), has a soft, but bright tone. It has that little bit more tension in the chord over c-7.

The notes in Cmin9 are:

D
Bb

G
Eb
C

The chord’s root ultimately determines the harmony. However, a lot of arpeggios have extra chords that you can refer to or play over the primary chord.

The simplest technique to invert this chord is to take off the bass note (C), which the bassist will cover. The resulting Eb7 chord contains 4 notes, which you can invert as per usual. 5 note chords cannot be inverted because the voicings are too close and would create too much tension.
