Playing with the rhythm of fiction: How commas and conjunctions affect rhythm and mood

This post shows you how you can use commas and conjunctions to alter the rhythm of a sentence. Changing the rhythm can help your readers immerse themselves deeper in the mood of your narrative and the emotions of your characters.

​Standard grammar advice

Standard grammar advice – the stuff we learned when we were kids – calls for lists with three or more items (or phrases or clauses) in a sentence to be separated by a comma, and for a conjunction to be inserted before the final item:

• Her arsenal of weapons included rifles, pistols and machetes.

Or, if your preference is to use the serial (or Oxford comma):

• Her arsenal of weapons included rifles, pistols, and machetes.

The use of this one conjunction is called syndeton, and it moderates the pace.

When it comes to fiction, standard grammar works very well for the most part. However, there are other accepted literary devices you can use to help your readers feel the scene you’ve written in a different way: asyndeton and polysyndeton.

I’ve used examples from crime fiction in this article but the principles apply across genres.

More on syndetic constructions

Syndeton is everywhere. It’s the most oft-used way of constructing a sentence with multiple clauses, and it works well because it aids clarity: this thing, that thing and that other thing.
​
Here’s an excerpt from At Risk by Stella Rimington (p. 369):

the display computer generated a red line on the map. It moved southwards from Dersthorpe Strand, crossed the blue line representing the roadblock, and passed through Birdhoe and Narborough to Marwell.

And here’s an example from Jo Nesbo’s first Harry Hole thriller, The Bat (p. 250):

‘They helped the Allies against the Germans and the Italians, the South Koreans against the North Koreans and the Americans against the Japanese and the North Vietnamese.’

The second excerpt is taken from a chapter in which the head of the crime squad, Neil McCormack, delivers a long speech to the protagonist, Harry Hole. Harry has just spent nearly an hour delivering his own monologue, updating McCormack on everything that’s happened so far.

The mood of the entire scene is one of contemplation and resignation. The characters give each other the space to talk without rushing. Their behaviour feels controlled, and the way they talk is measured.

The grammatical structure of the sentence (syndetic) is a good choice because it moderates the speed at which we read, and reflects the mood.

Omitting conjunctions – asyndeton

Authors might choose on occasion to change the mood of a sentence by deliberately removing the conjunction. Separating all the items with only commas accelerates the rhythm.

That speeding-up can have a variety of effects:

• Imparting emotions – for example, frustration, futility, despair, desperation, determination, fear, hysteria or urgency.
• Indicating that a person is speaking rapidly.
• Evoking a sense of dislocation by bringing clinical precision to the narrative.
• Adding weight to each clause, thereby increasing drama.

Let’s go back to the Nesbo example and see what happens when we change it:

‘They helped the Allies against the Germans and the Italians, the South Koreans against the North Koreans, the Americans against the Japanese and the North Vietnamese.’

By omitting the conjunction and inserting a comma, a sense of frustration and urgency is introduced. It’s subtle, certainly, but that’s the beauty of it.

If Nesbo had wanted to convey more immediacy, he could have elected to make these small changes. They would have altered the rhythm and showed (without spelling it out) that McCormack’s tone had changed or the pace of his speech had increased.

Here are two examples from Robert Ludlum’s The Janson Directive (p. 274 and p. 355):

He forced his eyes open again, took in the green vistas of Regent’s Park, looked at his watch. Two minutes had elapsed. The retention of consciousness itself would be a supreme effort, yet one at which he must not fail.

In the example above, Ludlum could have introduced ‘and’ after/instead of the final comma of the first sentence with no detrimental effects, but I think its omission brings a sense of urgency and determination to the writing that reflects the tension of the scene.

In the excerpt below, he uses asyndeton to evoke a sense of futility, frustration and anger. The reader is forced to become bogged down in the senseless loss of life from a bullet to the head:

Another dumb, inanimate slug would shatter another skull, and another life would be stricken, erased, turned into the putrid animal matter from which it had been constituted.

Asyndetic constructions can be particularly effective in noir and hardboiled crime fiction. These genres don’t shy away from the dark underbelly of their settings. The characters are often as damaged as the gritty environments they work within, and a sense of hollowness and futility underpins the novels.

Here’s an excerpt from The Little Sister (p. 177) by the king of hardboiled, Raymond Chandler:

I was a blank man. I had no face, no meaning, no personality, hardly a name. I didn’t want to eat. I didn’t even want a drink.

Imagine that second sentence with ‘and’ after (or instead of) the final comma. It would ruin the flow and remove the utter sense of despair and hopelessness. Chandler doesn’t overdo it though. He saves his use of the asyndetic for the right moments rather than littering his pages with it.

Using multiple conjunctions – polysyndeton

Another technique for altering rhythm is that of using multiple conjunctions. Polysyndetic constructions are interesting in that they can work both ways:

• You might introduce multiple conjunctions to evoke a sense of excitement or hysteria. In this case the pace would be accelerated.
• Or you might use them to create a sense of overwhelm. In this case the pace would be moderated as the reader is pulled into the mire of the narrative.

​In the following example, Chandler (p. 103) shows us two different groups of people waiting in a reception area that the main character, Philip Marlowe, has entered. By using a conjunction between each adjective describing the hopefuls, he enhances the brightness of their mood. This in turn tells us more than Chandler gives us in terms of words about the other group. We can imagine their boredom and frustration:

There was a flowered carpet, and a lot of people waiting to see Mr Sheridan Ballou. Some of them were bright and cheerful and full of hope. Some looked as if they had been there for days.

There’s a powerful example of the polysyndetic in Kate Hamer’s The Girl in the Red Coat (p. 151). Hamer uses it to enrich a child-character’s voice. Carmel has been abducted and is experiencing a kind of dislocation as she plays with two other children. The multiple conjunctions serve to emphasize the overwhelming giddiness. There’s almost no time to take a breath:

I play tea sets with the twins on a fold-up table and their voices go very fast and gabbling like chipmunks and they lift the cups to their lips and pretend to drink, over and over, and their hands move across the table, swapping things about so fast I feel dizzy.

Beware the comma splice

Asyndeton should not be confused with the comma splice.

A comma splice describes two independent clauses joined by a comma rather than a conjunction or an alternative punctuation mark. I recommend you avoid it because some readers will think it's an error and might leave negative reviews.

​The standard-punctuation column in the table below shows how the authors have got it just right. The right-hand column shows you how the non-standard comma-spliced versions would appear.

Author: Ludlum, p. 355

• ​​Standard punctuation: That was not progress; it was the very opposite.’​
• ​Comma splice: That was not progress, it was the very opposite.

Author: Rimington, p. 238

• ​​Standard punctuation: ​​​He was flushed. Sweat spots studded the pink expanse of his forehead.’​
• ​Comma splice: He was flushed, sweat spots studded the pink expanse of his forehead.

Author: ​Chandler, p. 119

• ​​Standard punctuation: ​I went past the two secretaries and down the corridor past the open door of Spink’s office. There was no sound in there, but I could smell his cigar smoke.
• ​Comma splice: I went past the two secretaries and down the corridor past the open door of Spink’s office. There was no sound in there, I could smell his cigar smoke.

​Made-up example

• ​​​Standard punctuation: He stopped, knelt down in the mud. [Asyndetic]
• ​Comma splice: ​He stopped, he knelt down in the mud.

Summing up

I hope this overview of syndeton, asyndeton, polysyndeton and the comma splice will help you to discover new ways of playing with the rhythm of your own writing while keeping the punctuation pedants at bay!
