The minor ninth chord extends m7 with a major ninth above the root (1-♭3-5-♭7-9). The ninth widens the voicing and adds a modern, singing color while preserving the minor-seventh identity. It is standard on ii9 progressions in jazz and appears frequently in R&B, neo-soul, and contemporary pop harmony.
Construction
Build from m7 by adding 9. In Cm9, include D as the ninth above C.
Usage
Rich ii chords, minor tonic extensions in modern styles, and smooth voice leading into dominant harmonies.
Examples
- ii9–V13–I in jazz standards
- Neo-soul keyboard pads on i9
- Pop progressions that substitute m9 for m7 for extra shimmer
Play
Omit the root or fifth in some voicings to keep clarity; keep the guide tones (♭3 and ♭7) present.
Ear-training cues
Minor seventh core with a bright ninth extension above.
