Voicings
Written in C, because that is the key the encyclopedia authors them in; every one transposes unchanged.
Root Position (no 3rd)
C · G · Bb · D · F
intermediate
LH C anchors the root; RH G-Bb-D-F. Dropping the 3rd is intentional — it keeps the 11 from clashing.
Rootless(b7-9-11-5)
Bb · D · F · G
intermediate
Right hand 1-2-3-5 on Bb-D-F-G. A simple Gm7 shape that the bass turns into C11.
Quartal Voicing
F · Bb · D · G
advanced
Stack from F: 1-2-3-5. Keep it even and open — let the fourths ring rather than the thirds.
Where it turns up
Gospel and soul cadences, the big 'amen' suspended dominant, and as a V chord that delays its resolution. Common in McCoy Tyner and gospel-piano vocabulary, and as the climax dominant before a I chord.
Commonly swapped with
- With the 3rd omitted, C11 is essentially Gm7/C
