Vocal folds, vocal chords, or vocal cords?

Let me start by saying that out of the tree ways to refer to the part of your body that generates sound, there is only one that is the anatomically and medically correct terminology and that is vocal folds.

There’s another one that is not as technical but still ok to use, and one that is a misspelling of the latter and being the educated choir singer that you are, you want to avoid using. So, which one’s the culprit?

Vocal Folds

The absolutely medically correct terminology is vocal folds. Thanks to tiny cameras that doctors use now-a-days, we know that we produce sound for speaking and singing when air causes two tiny membranes in our throat to vibrate, much like the skin of a drum.

Vocal folds, vocal cords, vocal chords

These membranes are called folds because they are made out of layers of mucous membrane much like phyllo dough on top of baklava. Don’t let the word mucous throw you off though (I know it’s not a pretty word, so let me use mm from now on).

An mm is called so, not because of what it produces, but because of its purpose in the body. These are membranes that protect all internal parts of the body that come in contact with the environment. So for example, the lining inside your mouth is also an mm.

But, who’s going to win in the battle of chords vs cords! If you want to impress others and look like the awesome chorister that you are, read on.

Vocal Cords

The less technically correct, but still ok word to use is cords; so vocal cords. I’m sure you want to know why that is, and why vocal chords is wrong, so here’s the story of how this came about.

It was 1741, when Antoine Ferrein, a French anatomist (he would probably be called an otolaryngologist today), came up with the term cordes vocales or vocal cords (doctors wrote in Latin at the time) to refer to the vocal folds. His idea was that vocal cords were the same as the cords of a violin or a guitar. I found this image that I think is close to what he had in mind.

Vocal Chords

As, you’ve figured out, vocal chords is the wrong one, even if you hear it and read it with the same frequency as vocal cords. It is pretty confusing taking in consideration that chord is a perfectly valid musical term.

Vocal chords, vocal cords, vocal foldsA chord is a group of two or more notes sang or played at the same time, as when a choir sings a song. The most popular use is probably when people refer to guitar chords. The confusion probably comes from the use of the word chord in geometry to refer to a line that links two points on a circle. But let’s not blame math, now.

So, use vocal folds and vocal cords, and as for vocal chords, that would be you and two more of your choir buddies singing a 3-note harmony.

  4. Are you serious? You wrote an entire article on how to spell “cords”??? I use them somewhat interchangeably, I admit- but refer to them as “vocal folds” in academic written literature, etc. Either way, what is important is that we learn how they function and how to take care of them. But I agree with the poster Brett- how can you write such a post on spelling when yours is not correct much of the time, either?

  5. HA! Get out of my head, Brett! I thought the same thing!

  6. I learned that mm is mucous membranes and its a tiny layer of skin that helps you sing. I will work on using my vocal cords to sing better.

  7. Vocal folds are layers of mucous membrane up in which help when singing or speaking. Much like the mouth, vocal folds are a layer in which protects the internal parts of the body.

  12. To sum up the article, it is about vocal folds, and what the difference between a vocal cord and a vocal chord is. Vocal folds are layers of mucus membrane that vibrate to produce sound and protect all internal parts of the body that come in contact with the environment. Antoine Ferrein (a French otolaryngologist) wrote cordes vocals to refer to the vocal folds. When singing the body uses vocal folds and vocal cords. However a chord would be a 3-note harmony because a chord is when a group of two or more notes are sang or played at the same time.

  13. In the article “vocal folds, vocal chords, vocal cords” they mention vocal folds, vocal chords, and vocal cords. A vocal fold is basically tiny membranes that are made up of mucus membrane much like phyllo doe on baclava. The difference between vocal chords and vocal cords is that the term vocal chords is incorrect. A chord is two or more notes played at once. In 1741 a man named Antoine Ferrein had a theory that vocal cords are the same as cords in a violin or a guitar. Therefore a vocal fold and a vocal cord are similar, but a vocal chord is more of a harmony.

  14. There’s a typo in the first line – ‘tree ways.’ The rest of it is fine. Thank you.

  15. While this is really informative, I disagree that “chords” is more wrong than “cords”. Since most people know how to spell “cords”, and about half (according to Wikipedia) people in the 21st century say/write “vocal chords”, they probably know they’re not describing literal cords, and are just using a well-established name for a complex system they don’t necessarily understand (and don’t need to, either).

    So cords and chords are equally correct (judging by how often they’re used), but someone using “cords” rather than “chords” is more likely to believe they’re literal cords, which would be incorrect, and “chords” users are unlikely to think they’re literal chords since both other uses of it are so abstract.
