Why is there this voicing over, say, just a Root 3rd and 5th? Is it just that it sounds better?

It doesn't sound inherently better or worse than the narrow root-3rd-5th voicing, just different. Somewhat palpably, a narrow-voiced chord will tend to sound intimate, focused, unitary, whereas a wide voicing will sound more open, dreamy or adventurous.

But the reason for a given voicing of one chord can usually not be reduced to just its sound as such, but to the musical context. In particular if you use only narrow chords in root position, you'll inevitably have a lot of big jumps in parallel movement. This can be used as a stylistic element; some guitarists just slide around one chord shape over the neck all of the time. But it sounds rather raw and unsophisticated.

What I mean is this: to play a progression like - - - with all narrow root-position chords, you need to do something like

%%score T1
V:T1           clef=treble
% 1
[V:T1] [CEG] [FAc] | [GBd] [ceg]

Note that the “average pitch” is completely different in each chord, giving a pretty jumpy sound. OTOH, there's not really a lot of variation of any more subtle, interesting kind.

Classical music and many styles after it strongly avoids this kind of parallel movement. In classical music, harmony isn't just understood as sequencing of chords but as a particular form of counterpoint between individual melodic voices. And this generally strives for smooth transitions with not too big jumps in each voice (unless as a deliberate effect), and tends to prefer contrary motion to parallel motion to “unglue” the voices. This is quite hard to do with only narrow voicings. So classically, the - - - progression would more likely be rendered something like

%%score T1 B1
V:T1           clef=treble
V:B1           clef=bass
% 1
[V:T1] [EG] [FA] | [DB] [Ec]
[V:B1] C    F,   | G,    C,

Much more coherent. (Notice that the F and final C chords don't include a fifth here; that is often not possible with only three voices in common-practice voice leading.)

    “In classical music, harmony isn't just understood as sequencing of chords but as a particular form of counterpoint between individual melodic voices.” That's so well-put! And so little understood… That sort of music isn't a sequence of chords, so much as a combination of parts, each with its own sequence of notes, and the way that chords arise from them. (If I had time, a diagram would help explain this.)

  • Wonderful! One way to demonstrate the idea would be to have three different human voices or three different instruments on the voices: then even an untrained ear could more easily distinguish the voices, and already this thought experiment without actual listening may help understanding how big a difference it makes.

    I guess you could say my thinking on chords was a tad narrow... Bad pun, I know, but the only way I could say it

There are probably countless reasons why you might choose to voice a chord this way; some which come to mind are:

1. Intervals like the third sometimes sound a bit muddy in the bass register, therefore one might wish to have more space between the root and the third. See this question for more detail.

2. It may arise due to the needs of proper voice leading. Depending on what comes before and after this chord, this voicing may well make for the smoothest/most pleasing transition.

3. These kinds of voicings are also common in Chorale harmonizations (examples) which are commonly used as a tool for teaching harmony and voice leading (see above), which might be what that lesson is setting you up for. Chorale harmonizations are often written on piano staves (and played on keyboard instruments), but ultimately originate as vocal music which leads to making slightly different choices than one would make in music written with a keyboard instrument in mind.

4. As you say, one might feel that it sounds better. The most important factor when describing chord voicings is generally the bass note, as it determines which inversion is being played, but there's generally more leeway in the placement of the upper intervals. This is often determined by wanting to have a certain note in the top (i.e. the melody) voice. It may also be said that adding doublings of the root (and to a lesser extent the fifth) tend to add "fullness" to the chord without affecting its function or overall character too much.

You should try experimenting with different voicings yourself and see how different ways of arranging the intervals sound to you. Music would be quite boring after all if every chord was arranged strictly in ascending order from the root.


There are already some good answers here, but since you ask specifically about piano, it's worth observing that this voicing fits perfectly under the hands and will be found in the literature countless times.


I often write four-part male voice arrangements and know that narrow-range harmonizations in too low a range produce a muddy sound. I keep the ranges as wide as possible without venturing into unreasonable extremes of range.


Yes, they might sound better

The timbre or tone quality of an instrument comes from the overtones or harmonic series that accompanies the fundamental note (the played note). Your hearing range impacts what overtones you can hear. When you play two notes together, there is some degree of dissonance, based on the notes and their respective overtones, and the range in which you can perceive them. An octave shares the most overtones, so has the least accompanying disonnance. Then the fifth, then the fourth, then the third, and so on, with the most dissonant being a minor second, assuming a 12 tone chromatic scale. These disonances are more pronounced in the lower register because you can perceive more of the overtones associated with each note. Thus it is common in piano music to write a chord with less dissonant intervals in the lower register.

It also may be written with a particular voicing for other reasons. For instance, to make it easier to play or to leave counterpoint a note open in the lead.
