Bees (playful) Frogs (ardent) Bats (unbelievably loud)

Reading A Book of Noises: Notes on the Auraculous by Caspar Henderson for the Spectator, 7 October 2023

Caspar Henderson writes beguiling commonplace books about the natural world, full of eye-catching detail and plangent commentary. His Book of Barely Imagined Beings: A 21st Century Bestiary came out in 2012. A Book of Noises is a worthy companion: a pursuit of auditory wonders, a paean to the act of listening, and a salute to silence.

Item: the music of the spheres. (The planets’ orbits, proving unideal and elliptical, suggested to the musically-minded astronomer Johannes Kepler an appropriately sad, minor-keyed Leitmotif for the Earth, “where, he felt, misery and famine held sway.”)

Item: the world’s loudest sound. (The asteroid Chicxulub, that killed the dinosaurs 66 million years ago; also an honourable mention to the Indonesian volcano Karakatoa, whose eruption in 1883 burst eardrums forty miles away).

Bees (playful). Frogs (ardent). Bats (unbelievably loud). The Magic Flute and the soundscapes of Hell. Sounds of the cosmos give way to sounds of the Earth. Life follows, bellowing, and humanity comes after, babbling and brandishing bells. The 48 forays into sound that make up A Book of Noises are arranged with the sort of guileless simplicity achievable only after the author-compiler has been beating their head against a wall for some years.

Everything trembles. The world sounds and resounds. Elephants flee the sound of helicopter blades turning eighty miles away. The root system of the common pea plant will move towards the sound of water in a pipe.

There’s something missing. If ever a book cried out for an accompanying Spotify playlist, it’s this one. Maybe I was looking too soon. Maybe a kind reader will put one together. What the heck, maybe I will. Ransacking this book affords hours of listening pleasure (or at any rate bemusement). Max Richter’s album Sleep to ease us in. Then Sam Perkins’s Alta for Two String Trios and Electronics, capturing the ephemeral crackles that sometimes accompany the Northern Lights. Dai Fujikura’s 2010 Glacier, which the composer describes as “a plume of cold air which is floating silently between the peaks of a very icy cold landscape, slowly but cutting like a knife.” Joseph Monkhouse’s soundscapes of the Somerset levels in the Iron Age. David Rothenberg’s quixotic saxophone duets with whales in 2008 stretched even Henderson’s famous generosity of spirit, and he writes: “it is hard to know how far, if at all, the whales are actually listening.” Such grounding moments are important, in a book chock-full of fancy.

The point is, the world makes sounds and we, at our best, make sounds of our own in response. For every natural wonder, there is probably an eccentric musical instrument gathering dust somewhere: for every frog, a flute; for every booming volcano, some variation on a horn. The sounds that humans make are rooted in a profoundly material soundworld. The extrapolated and bizarre soundworlds made possible by digital technology are still largely terra incognita, and there may be good reason for this. “One is humbly aware that [this digital soundworld] will only be conquered by penetration of the human spirit,” the British composer Jonathan Harvey is quoted as saying, “and that penetration will neither be rapid or easy.”

Music itself, as a technology and as an idea, sometimes imposes too narrow a filter over our experience of sound. In a striking (ha!) chapter on bells, Henderson explains that the bells in Russian churches are meant to be voices, not musical instruments. For that reason, they are quite deliberately untuned, so that they produce as many over- and undertones as possible.

Humanity at its worst, meanwhile, makes a din that deafens whales and stresses birds out of their minds and mating patterns. Henderson cites soundscape ecologist Bernie Krause’s twenty-year project to record the sounds at Sugarloaf Park in California — a dramatic and frankly depressing record of environmental diminution and fragmentation, speaking to “a catastrophic loss of sonic diversity and richness worldwide.” The story of our scraping of the planet is also part of Henderson’s story. This is not an altogether happy book.

Is it a wise one? This is Henderson’s clear and laudable ambition. One of the perils of writing a book like this is that, in order to make the contents readable in any order, you have to carefully top and tail every one of those forty-eight seemingly disconnected microchapters. The effort throws up gnomic and occasionally ponderous capstones that are a gift to the mean and cantankerous critic. In my notes here, the following closers: “Life calls to us even as we call to it.” / “If there is to be a future worth living in it will surely hold a place for re-enchantment.” / “While you live, shine.”

This sort of niggle only shows up on a fast read. Readers can and should take their time. It will be very well spent.

 

A surprisingly narrow piano

Reading Richard Mainwaring’s Everybody Hertz for the Spectator, 30 April 2022.

Imagine that all the frequencies nature affords were laid out on an extended piano keyboard. Never mind that some waves are mechanical, propagated through air or some other fluid, and other waves are electromagnetic, and can pass through a vacuum. Lay them down all together, and what do you get?

The startling answer is: a surprisingly narrow piano. To play X-rays (whose waves cycle up to 30,000,000,000,000,000,000 times per second), our pianist would have to travel a mere nine metres to the right of middle C. Wandering nine and a half metres in the other direction, our pianist would then be able to sound the super-bass note generated by shockwaves rippling through the hot gas around a supermassive black hole in the Perseus cluster — a wave that cycles just once every 18.5 million years.

Closer to home, how big do you think that piano would have to be for it to play every note distinguishable by the human ear? You’d have to add barely a single octave to either side of a regular concert grand.

Readers of Richard Mainwaring’s wonderfully titled book will fall into two camps. Some will want to hear what this “infinite piano” conceit reveals about the natural world; about the (considerable) auditory abilities of spiders, say, or how 23 high-stepping fitness junkies caused a tremor that evacuated the the 39-storey Techno Mart building in Seoul, South Korea.

Other readers, though entertained well enough by Mainwaring’s extraordinary clear and concise science writing, won’t be able to get that infinite piano out of their heads. It’s a metaphor so engaging, so intuitive, it’s quite as exciting as anything else in the book (for all that the book features ghosts, whales, Neolithic chambered cairns and Nikolai Tesla).

Mainwaring is a musician and a composer, and the business of music runs under even his most abstruse intellectual excursions. A Marsquake recorded on On 6 April 2019, sped up by a factor of 60, sounds, he tells us, “not unlike someone blowing over the top of a half-full wine bottle in Westminster Abbey”. Fully concentrating on a task generates brainwaves of around 40 Hz or more: ”it’s a wonder we can’t hear them humming, as they are at the same frequency as the opening bass note of Cypress Hill’s ‘Insane in the Brain’.”

This is infotainment at its most charming and lightweight; tonally, it’s of a piece with the musical stunts (for example, arranging a performance by massed tuning-forks) that Mainwaring has regularly staged for BBC1’s pre-watershed magazine programme The ONE Show. The glimpses Mainwaring gives us into the peculiar, fractured, distraction-filled business of modern music making are quite as fascinating as his tales of planetary resonance and the latest thinking about olfaction. He can also be tremendously catty, as when he pricks the vaingloriousness of virtuoso bass players (“Know your role, bassists – stay out of the way.”)

Like any ebullient teacher, he won’t be everybody’s cup of tea. There’s always one misery-guts at the back of the class whose teeth will be set on edge, and now and again Mainwaring’s humour is a little forced. This is usually because he’s hit on some neat metaphor and doesn’t know when to stop beating on it. We should set against this, though, his willingness to dive (and deeply, too) into any number of abstruse subjects, from religious experiences to Edwardian vibrators.

Throughout, Mainwaring keeps a sharp eye out for specious claims and pretensions. There is, he says, nothing magical about “the God-given, superhero ability of perfect pitch” — the ability to identify a note from its frequency. Indeed, before 1955, the year the ISO standardised “A” at 440 Hz, there was no such thing as perfect pitch. (Interestingly, though, speakers of Mandarin, a language dependent on tonal inflexion, are rather better at guessing notes than the rest of us.)

On the other hand there is, as Mainwaring ably demonstrates, an extraordinary spiritual power to music, particularly around the note A forty-seven white keys to the left of middle C. (That’s 19 cycles per second, or 19 Hertz, we say now, in honour of Heinrich Rudolf Hertz, who proved the existence of electromagnetic waves). This “A” can trigger cold sweats, fits of severe depression, and even sightings of dead people. Mainwaring traces the use of low notes and infrasound from the more inaccessible tunnels of French caves (where little ochre dots marked where prehistoric singers should stand to sound especially resonant and amplified) to Bach’s Toccata and Fugue in D Minor which, on any decent organ, generates infrasonic byproducts by means of two chords and a low pedal D.

Though horribly abused and exploited by various new Age fads over the years, the old intuition still holds: vibrations reveal much about life, consciousness and the integrity of matter. Mainwaring’s clear-eyed forays into medicine, psychology and spirituality reflect as much.

It’s a commonplace of popular science that the world is looked at best through this or that funny-shaped window of the author’s choosing. But Mainwaring’s garrulous offering is the real deal.

Electric Shadows

From 12-14 October 2012, the Kontraste Festival – curated by Sonic Acts – reverberates across Krems, a pretty town on the Danube famous for its art galleries, staggeringly good white wine, and one of the world’s best preserved panopticon prisons. On Saturday I’ll be discussing how, adapted as we are to a rich visual world, we will have to learn to tolerate the limited colour palette and visual monotony of the rest of the universe. This is one of the more left-field contributions; for the most part the weekend is filled with a wild assortment of scientifically literate sound artists Playing with Our Brains. This sort of thing:

There’s also a film programme, like this:

with a touch of this:

If you can’t make it up the Danube, there’s always the book.
