A few years ago the comedian Patrice O'Neal related a story in which he told about a bit he did regarding the D.C. Beltway sniper. The punchline of the bit was "N**** in a Buick," and, for whatever reason, the censors bleeped out the word "Buick," presumably because some advertiser didn't want their product associated with a sniper. What Mr. O'Neal discovered in the censoring, though, was that the joke was no longer funny, not without Buick. Why? Because, he observed, hard consonants are funny.
A couple of years before Patrice O'Neal's stand-up career, the philosopher Plato really stepped in it by unleashing a dialogue on the world ("Cratylus") whose content and ramifications everyone involved in language is still dealing with, even if they don't know it. If you speak and write, you have some experience of euphony (or the mangling of the same), which, for present purposes, is the quality of how words hit the ear, especially in combination, irrespective of what actual information is being conveyed. Everything from onomatopoeia to scansion and alliteration falls under the umbrella of the term.
"Euphonics" by John Michell (with illustrations by Merrily Harpur) is a light-hearted, not-too-serious look at the history and art of euphonics, taking the reader on an orthographic journey from A to Z (with some detours to explicate the effects of certain letter combinations).
The short book is almost like an Anglophile poet's Futhark, explicated in funny, whimsical (and sometimes crude) rhymes which get the point across that the sounds that constitute words convey meaning independent of the words themselves. Words with heavy "Z" sounds imply laziness, haziness, the confusion of a maze, for instance. A bunch of "S's" produce a sibilant effect that can remind one of something secretive, shameful, or perhaps slithering like a snake.
For all the book's playfulness, though, and despite its breezy style, it really is a thing of beauty. It's a reminder of the joy and genius of language, a genius that's native to all of us, but which sometimes needs a rekindling. You know a book is good when a kid in kindergarten or a Poet Laureate can get something from it. Highest recommendation.
