Chord voicings
The same chord can be spread across the keyboard in many ways. That distribution — which note sits at the bottom, which ones cluster on top, which are left out — is the chord’s *voicing*, and it changes its character completely without changing its name.
Triad over the root
The simplest way to open a chord up: the left hand plays only the root, an octave lower, while the right hand plays the full triad. Instead of three notes bunched together, the chord gains bass and depth.
Splitting bass from the rest
With four-note chords the same idea applies by splitting the chord in two: the left hand holds the root and the right hand plays the remaining three notes. Cmaj7 gains breadth from the gap left between the bass and the upper block.
Closed and open voicings
A closed voicing packs the notes into the smallest possible space; an open voicing spreads them across a wide register. The same C11 allows both, and they do not sound alike: the closed one is dense and a little muddy, the open one breathes.
Within a progression it pays to alternate them: moving from closed to open creates motion without changing chord. A practical rule: when several notes end up close together, they sound better in the middle of the chord than at the bottom.
Rootless voicings
A chord without its root looks like a contradiction, but it works: if the third and the seventh are there, the ear fills in the rest. The chord is implied.
Why do it? First, it frees a finger: the note you drop can be replaced by a ninth or a thirteenth, so the chord gains colour without gaining notes. Second, when there is a bass player or a busy left hand, the root is already sounding elsewhere.
This is the door to substitutions: if a chord can be implied rather than played in full, it can also be replaced by a similar one. That is covered in chord substitutions.
