A Look at the Yod a.k.a the J-Glide

A common point of confusion in French Lyric Diction is knowing when to pronounce the -ill(es), -il(s) as a Yod [j], and when do we pronounce this double “ll” combo as just one “l” [l]. There is a method to this madness, and it is not so complicated.

If the term”Yod” or “j-glide” is stumping you, you can check out one of my past blog posts on the subject of semi-consonants to catch up!

First, we should look at when we pronounce “i” as a Yod.

i or ï is pronounced as a [j] when preceded by a single consonant when it is in front of an a, e, o, or eu. Beware: not when it is in the middle of a word -ie- in some verbs and their derivatives or as the last sound of the word -ie.

For example:

Avant de quitter ces lieux, sol natal de mes aïeux (Before leaving this place, native soil of my ancestors), Valentin’s aria from Faust by Gounod

[aˈvɑ̃ də kiˈte sɛ ljø sɔl naˈtal də mɛz‿aˈjø]

In the example above, in the words “lieux” and “aïeux”, the i and ï are pronounced as a glide. Both of these vowels are in front of eu.

But we do not make a glide in the future tense conjugation of verbs like “oublier” (to forget) [ubliˈe]

J’oublierai (I shall forget) also does not have a glide; in fact, the e vanishes in pronunciation. I often hear [ʒubliəˈre], but the correct way to pronounce this word and other words like it is: [ʒubliˈre]

When -ie- is at the end of a word, it is simply [i] unless the composer gave a note value to the schwa, in which case it will be [iə], and we should not hear a glide between these vowels.

il, ill, ll : When do these letters make a Yod?

  • il, ill, and ll make a glide when at the end of a word in the following combinations: -ail,-eil, -ueil, -oeil- and euil.
  • il sounds as a glide in the middle of words in the following combinations: -aill-, -eill-, -euill-, -ouill-, -ueill- and oeill otherwise, it is pronounced as [ij].

Examples:

Un deuil amer (bitter mourning) [œ̃dœj‿aˈmɛr]

but in the word fille, we add an [i] in front of the glide; otherwise, there would be no vowel in the word: jeune fille (young girl) [ʒœnə fijə]

List of Exceptions:

As anyone who has ever studied the French language or French diction knows, there are many rules to follow, but there are just as many exceptions to the rules, if not more.

When il(s) is at the end of a word and follows a consonant, the i is [i], and the l is sometimes silent and sometimes sounded.

The following is pronounced without an l or a glide.

  • gentil (nice) [ʒɑ̃ˈti] N.B: You should not confuse this gentil with its feminine version gentille [ʒɑ̃ˈtijə] which is pronounced with a glide.
  • fusil (gun) [fy’zi]
  • grésil (hail) [gre’zi]
  • sourcil (eyebrow) [sur’si]

The following is pronounced without a glide but with an l

  • cil (eyelash) [sil]
  • fil (thread) [fil] or fils [fil] (the plural form of thread and pronounced exactly the same as the singular form) and not to be confused with fils (son or sons) [fis], which is pronounced without an l, but with an s whether it be singular or plural.

You could memorize this list, consult a French dictionary for the IPA translation on these more special words, or refer back to this post.

The exception also applies to the ll in the following words and their derivatives:

  • mille (thousand) [milə] Derivatives: million, milliers, milliards…
  • ville (city) [vilə] Derivatives: village, villageois, villagoise
  • tranquille (tranquil) [trɑ̃ˈkilə] Derivatives: tranquillité, tranquillement

If you don’t want to forget, memorize this phrase: Milles villes tranquilles: “A thousand tranquil cities” then you will remember that every word belonging to the family of these three words in French are pronounced as [l] rather than a [j].

These tips should help you navigate the world of “glide or not to glide” when it comes to the YOd and how to avoid making mistakes while singing, or speaking!

My favorite French dictionary online

We don’t always have a dictionary in our pockets, and let’s face the fact that we are in a digital age, no matter how much we love actual books. My favorite French dictionary online is the Larousse: https://www.larousse.fr/ This dictionary has been my go-to since as long as I can remember, it has it all, and the online version is quite good to work with.

Vocalic Harmonization in French Singing

What is Vocalic Harmonization?

Maybe you have heard this term before, or perhaps it is new to you. When I coach people for the first time, it always seems like they are familiar with Vocalic Harmonization, but they are not sure how to use it. It is a term used in linguistics when applying the rhyming of closely related vowels in the same or words that follow each other. It is also known as “vowel harmony”. The practice of vocalic harmonization is most often used in the French vocal repertoire for linguistic refinement and ease of vocal production. Most frequently in French singing, we harmonize [ɛ] with [e] and [œ] with [ø]

For example:  “aimer” [ɛˈme] becomes [eˈme] or Heureux [œˈrø] becomes [øˈrø]

As you can see in the examples above, the unstressed, open vowel-sound closes to rhyme with the following stressed, closed vowel, not the opposite. Remember, it is the final syllable that is stressed in French, except when that syllable is a schwa-sound [ə] because a schwa can never be stressed. In this case it is the syllable before the schwa that gets the stress.

les, tes, ses, mes, ces…

the possibility of vocalic harmonization also exists in closing the [ɛ] in short words such as les, tes, ces, etc. (these are articles or possessive adjectives). When a closed vowel immediately follows these, they can be closed to an [e].

For example: les étés [lɛz‿eˈte] would become [lez‿eˈte]

The article “les” is harmonized to the closed [e] in “étés”

These harmonized syllables must never be accented or overly closed, and at times they only are slightly closed on the way to their closed neighboring vowel-sound, and over-closing the harmonized vowel can result in obscuring the text. The idea is that it should feel natural and sound authentic since vocalic harmonization occurs in everyday speech but not deliberately. Many native French speakers do not even realize that they are doing this.

Some French words are almost always harmonized. For example, the following words would have all open vowels in the first syllable if we followed the diction rules, but they are sung and spoken with vocalic harmonization:


aimer (to love) [ɛˈme] becomes [eˈme]
baiser (to kiss) [bɛˈze] becomes [beˈze]
heureux (or heureuse) (happy) [œˈrø] becomes [øˈrø]


Vowel harmonization should not be systematic. It is a completely optional choice left to the singer. In cases where it can help the legato line, it is recommended to harmonize the vowels as sometimes it is easier to get through a phrase with fewer vowel changes.

For example:

Let’s take a look at “Lydia” by Fauré. In this text we find this line: “Laisse tes baisers de colombe”

The “tes baisers” can be sung as all closed [e] but the “laisse”” remains an open [ɛ] because the vowel following it is not a closed vowel.

[lɛsə tɛ bɛˈze] becomes [lɛsə te bɛeze]

Speak it out loud both ways and see the difference for yourself.

I would also go further and say if you have an article or possessive adjective (les, des, mes, tes ses) and the following word begins with a closed [o] or any vowel that has a closed feeling such as [i], [ø] [õ] [y] or [o], you can apply vocalic harmonization.

Again in in “Lydia by Fauré:

“Lydia, sur tes roses joues” you can harmonize the “tes” which would typically be [tɛ] to a closed [te] to match the closed [o] sounds of [rozə]. But, the “mes” in “mes amours” in the same song stays [ɛ] because a closed vowel-sound does not follow it.

Here is the text of Fauré’s Lydia where I will highlight the vocalic harmonizations:

Lydia, sur tes roses joues
Et sur ton col frais et si blanc
Roule étincelant
L’or fluide que tu dénoues;
Le jour qui lui est le meilleur
Oublions l’éternelle tombe
Laisse tes baisers de colombe
Chanter sur ta lèvre en fleur.
Un lys caché répand sans cesse
Une odeur divine en ton sein;
Les délices comme un essaim
Sortent de toi, jeune déesse
Je t’aime et meurs, ô mes amours,
Mon âme en baisers m’est ravie
O Lydia, rends-moi la vie,
Que je puisse mourir toujours!

In this recording of Véronique Gens and Roger Vignoles, you can hear the use of vocalic harmonization as highlightede above.

Try not to over-use vocalic harmonization. Remember, it should not obscure the text, and it should be helpful to the singing. If you are not sure if something should be harmonized or not, ask your French diction coach, or listen to several recordings to see what the consensus is. Just know that some coaches don’t apply vowel harmony and there are differing opinions on the matter. Since it happens in everyday speech, and I have seen it help so many singers in their legato and ease of singing, I generally encourage vocalic harmonization when appropriate.
