The major ninth chord extends maj7 with a major ninth (1-3-5-7-9). It is one of the most common “pretty” jazz and pop colors: stable like maj7, but wider and more singing because of the ninth. It appears on Imaj9, IVmaj9, and many turnaround voicings depending on bass motion.
Construction
Formula: 1-3-5-7-9. In Cmaj9, include D as the ninth.
Usage
Ballad tonic colors, neo-soul pads, and jazz standards where the chart calls for a lush major chord.
Examples
- Imaj9 openings
- R&B guitar voicings with high ninth sparkle
- Pop choruses that substitute maj9 for maj7
Play
Omit the root in some ensembles; keep 3 and 7 clear; place the ninth where it sings.
Ear-training cues
Major seventh core with a bright ninth above.
