Sound Devices and Other Techniques

Sound devices are the easiest techniques to spot and the hardest to analyse well, because it is tempting to write that alliteration "makes it flow" and stop. It does not make it flow. It does something specific, and identifying what is where the marks are.

Sound Devices

Technique	Definition	Example
Alliteration	Repetition of a consonant sound at the start of words	"The dark, damp dungeon"
Onomatopoeia	Words that sound like what they describe	buzz, crash, sizzle
Sibilance	Repetition of 's' sounds — creates a hissing effect	"Softly she slipped into the shadows"
Assonance	Repetition of vowel sounds	"The rain in Spain stays mainly"
Plosives	Hard 'b', 'p', 'd', 't' sounds — abrupt and forceful	"The brutal, bitter blast"
Consonance	Repeated consonant sounds anywhere in the words	"pitter patter"

The sound has to match the meaning

The key analytical move is to connect the type of sound to the effect being created. Not all alliteration does the same thing.

• Sibilance hisses, so it suits secrecy, menace, snakes, whispering, or something sinister and quiet
• Plosives burst, so they suit violence, anger, sudden impact, or harshness
• Soft consonants — l, m, n — feel gentle and slow, so they suit calm, tenderness or drowsiness
• Long vowel sounds slow a line down; short vowels speed it up

So "the dark, damp dungeon" is not just alliterative — the repeated d is a plosive, giving the phrase a heavy, thudding quality that suits an oppressive space. That sentence would score; "the writer uses alliteration to make it memorable" would not.

Onomatopoeia beyond the obvious

Students reach for bang, crash and buzz, but the more interesting examples are the words that only half sound like their meaning — murmur, rustle, clatter, squelch. These reward analysis because you can discuss how the word's sound reinforces its sense without simply imitating it.

Other Important Techniques

• Repetition — emphasises an idea or creates rhythm
• Rhetorical question — a question asked for effect, not a literal answer
• Rule of three / tricolon — three items in a row for rhythm and emphasis
• Juxtaposition — placing contrasting ideas together for effect
• Oxymoron — two contradictory words together: bitter-sweet
• Anaphora — repeating the same phrase at the start of successive sentences or clauses
• Antithesis — balancing two opposed ideas in parallel structure

Why the rule of three works

Three is the smallest number that establishes a pattern, which is why it feels complete in a way that two does not and four does not improve on. It appears constantly in speeches and persuasive writing for exactly that reason.

It is also a structure you can use deliberately in your own writing, and it is one of the quickest ways to make a sentence sound controlled.

The variant worth knowing is where the third item breaks the pattern — "it was cold, it was late, and it was entirely my fault" — because the surprise lands on the item the writer most wants you to notice.

Rhetorical questions — a warning

These are heavily overused in student writing, and examiners see them constantly. One well-placed rhetorical question is effective; four in an essay reads as a tic.

When analysing one, be specific about what it does: it can position the reader as already agreeing, make disagreement feel unreasonable, or create the impression of a conversation. "It makes the reader think" is too vague to score.

Worked example

"Softly she slipped into the shadows, silent as the settling snow."

A full analysis: the sibilance running through "softly", "slipped", "silent", "settling" and "snow" creates a hushed, whispering sound that mirrors the quietness being described, so the sentence performs the silence rather than merely reporting it. The simile comparing her to settling snow adds weightlessness and a suggestion of cold, while "settling" implies something gradual and unnoticed. Together the sound and the image position the reader as an observer who might easily have missed her.

Common mistakes

• "It makes it flow" — the single most common empty phrase in the subject
• Spotting alliteration without identifying what kind of sound it is
• Overusing rhetorical questions in your own writing
• Claiming an effect the sound does not support — not every alliteration is sinister
• Listing four techniques rather than analysing one properly

Exam tips

• Always link the type of sound to the mood — plosives to harshness, sibilance to secrecy
• Read the quotation aloud in your head; you will hear the effect before you can name it
• Analyse one device in depth rather than listing several
• In your own writing, use the rule of three and vary sentence length — both are quick wins for technical marks

Key facts to remember

• The kind of sound determines the effect: plosives are harsh, sibilance is hushed, soft consonants are gentle
• Never write "it makes it flow" — say what the sound actually does
• The rule of three works because three is the smallest complete pattern
• Rhetorical questions are effective in ones, not fours
• One device analysed properly beats four devices named
