In days gone by I was, for many years, a technology journalist. Over the course of a couple of decades I wrote several thousand articles for newspapers and computer publications in Australia, the USA and the UK.

The main focus of my writing was to explain, in plain English, the ins and outs of operating systems, applications—including word processors, databases, spreadsheets and graphics programs—and, when it began to get public traction, the Internet. I was also a computer programmer and, as a journalistic sideline, I wrote articles on coding and how to create applications that were, as they say, “user friendly.”

Although for the past 20 years my writing has been contained within the very different sphere of criminal justice, there’s a common element that has run through my entire writing output: music. Or, more specifically, cadence.

If music be the food of love, play on

When I write anything—from a birthday card to a Facebook post, from an article on database design to an opinion piece on the privatization of prisons—I listen for the flow of words into phrases, of phrases into sentences, of sentences into paragraphs.

When I rewrite, it is this flow that guides my edits.

Sometimes I want the flow to be smooth and swift, carrying the reader from beginning to end without hesitation. At other times, I am abrupt. Truncated. Forcing a pause or placing emphasis.

There are no rules for cadence in writing. The lilt is the author’s trademark, but not their straitjacket. It must make room for characterization and for the intent of the piece, just as Shakespeare took the fine tool that is iambic pentameter—de dum, de dum, de dum, de dum, de dum—and messed with it to suit his purposes.
