C Minor add ninth

The minor add9 chord adds a major ninth to a minor triad without adding a seventh in the symbol (1-♭3-5-9). Compared with m9, it feels more open and less “jazz-standard ii” because the missing seventh avoids the strong pull of ♭7. It is popular in alternative rock, R&B, and cinematic pop for shimmering minor textures.

Construction

Formula: 1-♭3-5-9. In Cm(add9), include D as the ninth.

Usage

Minor loops, guitar arpeggios, and pads where you want width without dominant-function tension.

Examples

• Pop production on i(add9) loops
• Guitar-driven verses with ringing ninths
• Neo-soul chords that alternate m7 and m(add9)

Play

Separate root and ninth when possible; omit the fifth in dense guitar voicings if needed.

Ear-training cues
