C Dominant eleventh

The dominant eleventh chord expands dominant harmony beyond the seventh and ninth, adding an eleventh color tone. It creates a broad, layered tension that sounds modern and spacious when voiced carefully.

Construction

The complete theoretical stack is 1-3-5-♭7-9-11. In C11: C-E-G-B♭-D-F. In practical arranging, players often omit tones like the fifth or even the ninth to avoid muddiness and highlight function.

Usage

Dominant eleventh sonorities are common in jazz, fusion, neo-soul, and cinematic writing where you want dominant direction plus harmonic depth.

Examples

• Jazz and fusion - extended dominant pads before cadence
• Neo-soul voicings - wide keyboard or guitar textures
• Film scoring - tense but airy harmonic motion

In practice

Protect the guide tones (3 and ♭7), then add 9/11 as color tones in clear registers so the chord stays functional and readable.
