Jazz Guitar Shell Voicings: Root, Third & Seventh
Muted strings are part of a clean voicing. A shell intentionally omits the fifth.
Shell voicings: root, third and seventh · By Vincent Iannone · Updated
What is a shell voicing on guitar?
A shell voicing is a three-note chord that plays only the root, third and seventh (or sixth). The fifth is left out because it says little about the chord’s quality, and leaving it out keeps the grip small and leaves room for a melody or soloist. Most shells use two string sets. With the root on string 5, the order is root, third, seventh: Dm7 is x-5-3-5-x-x (D3, F3, C4). With the root on string 6, the seventh sits below the third: G7 is 3-x-3-4-x-x (G2, F3, B3). Every string not in the shape is muted on purpose. Because shells are movable, a handful of grips covers major sevenths, minor sevenths and dominant sevenths in every key.
The idea
A shell uses the root, third, and seventh. The fifth can be omitted because it usually adds less information about chord quality. Three notes are enough to outline the harmony and leave space for a melody.
Put it under your fingers
- Play Dm7 as x-5-3-5-x-x from string 6 to string 1: D3 F3 C4.
- Mute unused strings. Pick the three sounding strings individually, then together.
- Hear the Dm7 shell in the play-along and match them without squeezing the neck.
Three notes make a Dm7 shell
D3-F3-C4 is the root, minor third, and minor seventh of Dm7. Hear them separately, then play x-5-3-5-x-x together.
Sounding notes: D3 → F3 → C4.
| # | Sounding note | Move from the previous note |
|---|---|---|
| 1 | D3 | Starting note |
| 2 | F3 | Up 3 semitones |
| 3 | C4 | Up 7 semitones |
Make it yours
Strum the Dm7 shell softly four times. Make the muted strings stay silent.
