Alliteration and Assonance

On this page we will look at patterns of sounds and the kinds of effect they can have in poems. First of all, though, we need to know what count as alliteration, assonance and rhyme. This may seem so obvious as not to be worth considering, but in fact things are a bit more complex than they first appear.

What are alliteration and assonance? - Same or similar single sounds?

Alliteration is usually described as the repetition of the same consonants, and assonance as the repetition of the same vowels. But we will argue below (i) that some identical sound repetitions do not count as alliteration or assonance and (ii) that sometimes 'repetitions' which are similar but not identical do count sometimes. Interestingly, students of poetry don't have much trouble in accepting that rhymes do not always have to be exact (cf. terms like 'half-rhyme', 'partial-rhyme', 'semi-rhyme' and 'para-rhyme'), and this should prepare us for the idea that alliteration and assonance do not always have to be exact either.

Task A: Consonants and Vowels

What is it that distinguishes consonants from vowels (and therefore alliteration from assonance)? How can we define them? Discuss these questions with your partner and type your answer below. Then compare it with what we say.

All speech sounds in English are produced by 'interfering' with the air flow in some was as it comes out from the lungs, through the throat, mouth and nose.

Consonants

To form the various consonants, we physically impede the air flow in some way, using the tongue, teeth and lips, as the air passes through the mouth cavity. So, for example, /b/ is formed by stopping the air flow momentarily and entirely with the two lips, whereas for /k/ it is stopped by pushing the blade of the tongue against the velum (soft palate). /b/ and /k/ are both called stop consonants because the air flow is stopped entirely for a moment. To form a /v/, we impede the air-flow with the top teeth and bottom lips, but we do not stop it entirely. Instead, it is continuously forced through the point of contact between the teeth and lips. These sorts of sounds are called fricatives.

Other consonants can be distinguished from one another by virtue of whether or not they are voiced. Voicing is produced by constricting the vocal chords in the larynx (Adam's apple), causing extra turbulence in the air flow. Lots of English consonants are in voiced/voiceless pairs, So, for example, /s/ and /f/ are voiceless but /z/ and /v/, which are impeded in the same places in the mouth, are not. If you are not sure of the difference, put your fingers firmly in your ears, start saying /s/ and change it to /z/. Then do the same thing with /f/ and /v/. Go on, do it!

Vowels

For vowels, unlike consonants, we do not impede the air flow. We merely alter the shape of our mouth cavity (try changing very slowly, without stopping, from saying /i:/ to /u:/ to /ɑ:/ and you should be able to notice that for /i:/ you push the blade of your tongue forward and up to the roof of your mouth, leaving a little space high in the mouth and to the front to produce the vowel sound. For /u:/ you round your lips and lower slightly the blade of the tongue, but not the front (so that the sound can occupy the high back portion of the mouth cavity). For /ɑ:/ the tongue drops to the bottom of your mouth and you open your mouth wide. This is why, if doctors wants to examine your throat they always ask you to say /ɑ:/, not /i:/!
