The major thirteenth chord extends maj7 with upper extensions typically including 9, 11, and 13 (1-3-5-7-9-11-13 as a conceptual set). The 13 (same pitch class as 6) adds warmth and forward motion on top of the major seventh’s stability. It is a hallmark of jazz, funk, and gospel voicings on I chords, IV chords, and dominant preparations depending on bass motion.
Construction
Extend maj7 by thirds in chord-symbol logic. Real voicings often omit the root, third, or fifth to avoid mud.
Usage
Lush tonic colors, IV13 grooves, and turnaround harmony.
Examples
- Herbie-style major and IV voicings
- Funk keyboard pads on maj13
- Gospel upper-structure stacks
Play
Choose which extensions to foreground; prioritize the sound over literal completeness.
Ear-training cues
Major seventh core with a major sixth/13 lift and wider extensions above.
