PRELUDE

Echoes of the Past

It is sixteen thousand years ago, and the plains teem with life. With the presence of the giant armadillo, American cheetahs, saber-toothed tigers, giant beavers, mastodons, camels, caribou, dire wolves, and ground sloths that stand as high as fourteen feet on their hind legs, wildlife is everywhere. Humans haven't made their appearance in North America yet, but birds in great numbers—including pied-billed grebes, storks, Canada geese, ducks, teals, common crows, turkeys, bobwhites, and dowitchers—fill the air with flight and song, while tree frogs, peepers, insects, and reptiles saturate the sound field with the intricate tapestry of their voices.

It is the end of an ice age, and the leading edge of the massive Wisconsin glacier slowly recedes to the Arctic Circle. With the earth's warming, the floral world thrives. Pine, oak, and spruce trees, along with larch, aspen, balsam, and poplar, have advanced far to the north along with low-lying shrubs and grasses. The first signs of the boreal forest have taken root in the Western Hemisphere—it thrives through the cold winters and the warm summers, and it is jam-packed with nonhuman life, whose individual voices coalesce into an intense and collective symphony.

In the heart of the young forest, an area surrounding a small stream is luxuriant and green, set under a deep-blue sky with a few tufted clouds; it is infused with the gentle warmth of a summer breeze. This habitat is densely populated with creature life; in fact, at this time, animal life—both numbers of species and individual creatures—is at a numerical peak in our planet's history. In this one verdant spot thousands of creatures sing in choruses at all times of the day and night. The visual spectacle is impressive, but the sound is absolutely glorious.

This place conveys a complex sonic narrative loaded with significant messages for any sentient being within earshot. The sounds expand to their greatest volumes at dawn and dusk—a loud-soft-loud progression that would be familiar to modern listeners of many styles of music.

Animals are hooting, bleating, growling, chirping, warbling, cooing. They are tweeting, clucking, humming, clicking, moaning, howling, screaming, peeping, sighing, whistling, mewing, croaking, gurgling, panting, barking, purring, squawking, buzzing, shrieking, stridulating, cawing, hissing, scratching, belching, cackling, singing melodies, stomping feet, leaping in and through the air, and beating wings—and doing it in a way that each voice can be heard distinctly, so that the animals seem able to hear and to distinguish one voice from another. The only sound louder than their collective chorusing is the howling wind of a great storm, a clap of thunder, an erupting volcano. The sound of water—a nearby stream—is the one constant nonbiological acoustic signature of the surroundings.

Then the ground shifts unexpectedly; a low, ominous rumble causes leaves in the upper stories of the trees to rustle for a moment like hundreds of muted castanets. Groups of insects and frogs suddenly become very quiet. But birds cry out, abandoning their well-ordered choral hierarchy and scattering in every direction; the air above explodes with the rush of staccato-like wing beats and cries of alarm. Throughout every fiber of each animal courses a sense of unfamiliar danger. Roaming predators steal into view, magnifying the tension of the moment.

Each organism is enveloped in more waves of sonic energy—great vibrations that come from everywhere—above, around, and below the ground itself. Predators take advantage of the moment to pursue those that are less agile and stunned by the earth's motion. The dominant opportunists—the lions, bears, raptors, and teratorns (with a wingspan of sixteen feet)—generate thundering footfalls and powerful edge-tones from fluttering wings as they propel themselves into the air and crash through the vegetation after their doubly terrified prey. Then come the final cries of the vanquished, a new message that punctuates the moment.

The world's waters—its oceans, lakes, rivers, estuaries, and coastal mangrove swamps—are packed full with fish, amphibians, reptiles, mollusks, mammals, and crustaceans, along with anemones and calcium carbonate coral structures that nurture and shelter many communities of smaller organisms. The ecosystems that rely on the contributions of marine organisms mark every shore. Like the habitats on land, these, too, are bursting with sound.

The Gulf of St. Lawrence, where that river and the Atlantic join, is home to thousands of species. The typical cod measures six or seven feet in length and weighs more than two hundred pounds. But it can hardly swim any distance without careening into another body, the waters are so vividly heaving with fish. Some bluefin tuna outstrip the cod, with adults measuring more than twelve feet long and weighing over fifteen hundred pounds. Plentiful, too, are the smaller herring and haddock, capelin, salmon, halibut, mackerel, shad, sea turtles, and even tiny smelt. Upriver are the striped bass, sturgeon—individuals can weigh as much as a thousand pounds—and trout. The ocean-dwelling fish supply food sources for the seals, dolphins, and larger toothed whales, while their baleen counterparts rely on krill, copepods, euphausiids, and cyprids.

Abundant sound is complete across the breadth of this marine environment. Some of the fish create acoustic signals with their swim bladders. Others signify their presence by gnashing their teeth. But each fish species generates a unique pressure wave through the oscillation of its tail fin—a signature sound recognized by others in the gulf, especially predators. With water limiting vision, sound is crucial to these animals' survival and reproduction, just as it is on land. From animals as small as protozoa, copepods, and phytoplankton to large whales, each species creates an acoustic sound-mark. The world's waters are saturated with living chatter, sighs, drumming, glissandos, cries, groans, grunts, and clicks.

Closer to the equator, coral reefs abound and make up a significant living mass. And they, too, pulsate with sound. Anemones, damselfish, three-spot dascyllus, and clown fish; parrot fish, wrasses, puffers, cardinalfish, grunts, triggerfish, fusiliers, goatfish, butterfly fish, red drum fish, many kinds of surgeonfish, jacks, sharks, snapping shrimp, and black drum fish—each leaves a distinct acoustic impression that, when combined with the others, forms part of a chorus that is set in the subtle acoustic background ambience generated by waves at the surface. Out in the open ocean, the songs of humpback, blue, and right whales are so loud that if unimpeded by landmasses—and when weather and ocean-current conditions conspire to moments of perfection—their voices could circle the earth in just under seven hours. The only sound louder than this combined contingent of mammals, fish, and crustaceans is the raging effect of a hurricane, typhoon, or tsunami.

The ready food supply in this marine environment supports an abundance of shorebird populations and, in the process, the attendant racket. There is the great auk—also called a spearbill—a stately flightless creature that has long since abandoned the air, given that it is a great swimmer. Nearby ocean-based food is so plentiful that it need not waste valuable energy flying to distant places. Then there's the raucous ow-ow-ow of the shearwaters mixed with the unique voices of puffins, gulls, terns, gannets, petrels, skuas, kittiwakes, fulmers, murres, and cormorants, creating a din that seems to make each vocalist indistinguishable from another. But it's a curious deception: these are the sounds of survival, reproduction, and communication, and each species has evolved so that it is heard distinctly among the others—and so that it projects over the thunderous, turbulent sounds of the ocean waves.

Mangrove swamps—saline woodlands that hug the subtropical and tropical coastal waters of every continent except the Antarctic—pulsate with curious mixes of insects, mammals, birds, and crustaceans. As the tides recede in these Mesoamerican biomes, crabs lose their grip on the branches and trunks of trees, falling with the distinctive plop of a large, flat, round stone into the exposed muddy sediment below. The crabs will return to the trunks and branches when they become submerged again, on the next incoming tide. When night falls, frog choruses swell and bats ping their echolocation signals in order to find edible insects in the dark. Barnacles clinging to the exposed rocks and mangrove roots twist noisily in their shells, causing tiny high popping sounds that resonate throughout the habitat above and below the waterline. Even at night, when the creatures are enveloped in darkness, many voices persist, competing for recognition.

Glacial ice still covers much of the planet north of the Arctic Circle, even as the planet warms. It's a cold and desolate place, five to ten degrees colder than it will be some sixteen millennia from now. The receding layers of ice carry with them spores and seeds from the recovered landscape. While these will impregnate the moraine once it becomes fertile enough to spawn the boreal forests of the Arctic's future, there is not much acoustic life on the surface. But even this environment is not quiet: explosive sounds occur when crevasses—deep elongated cracks—form in the glacial span. The ice mass shatters as it is compressed under great pressure and undergoes periods of melting and snow accumulation, and in addition to the startling popping and groaning of the ice and the ever-present wind and frequent storms, calving glaciers release huge walls of frozen water into the shorelines of rivers, fjords, and seacoasts with a volatile, thunderous burst of sound, the fallen accumulation generating huge waves in the water below. Then there is the sound of the glacier's own movement: a slight, ominous oscillation caused by its relentless progression overland—a slow, creeping sensation more felt than heard.

Just about halfway to the opposite pole, far from the receding edge of the ice and located within a few degrees of the equator, the tropical rain forests are the most densely populated biological provinces on the planet. Here, too, the vegetation and animal life are adapting to the warming earth, some species being replaced by others better suited to the new climate—but animal and plant life flourish here to an extent that it is difficult to imagine having room for one more species of anything. Rain forests cover nearly 15 percent of the earth's surface and contain an estimated fifteen to twenty million species of plants and animals. The sound there is riotous.

Mammals, reptiles, and amphibians—from jaguars and spectacled bears to crocodiles and even some frogs—vocalize in relatively low ranges, while other frogs and some birds warble and thrum in the lower-mid range. Still others—insects, along with more frogs, birds, and mammals—have established their voices in the high-mid and upper ranges. So many creature voices scream for attention at such a high volume, it seems miraculous that any one animal can hear another of the same clan, let alone make out the sound of another species, whether friend or foe.

The planet itself teems with a vigorous resonance that is as complete and expansive as it is delicately balanced. Every place, with its vast populations of plants and animals, becomes a concert hall, and everywhere a unique orchestra performs an unmatched symphony, with each species' sound fitting into a specific part of the score. It is a highly evolved, naturally wrought masterpiece.

Humans, too, are making their sound heard. They are dispersing now, spreading across the planet, leaving behind tangible, visible, and acoustic symbols of their presence wherever they go—detailed pictographs and petroglyphs, bone instruments, hunting and skinning tools, and evidence of larders to store excess grain, which they've managed to harvest from early seed plantings. They're pulling together in larger and larger groups, but basically they're still hunters. The forest is whispering to them, luring them in and revealing where the objects of their hunt can be found. At this stage of their development, sound-rich habitats are humans' most significant acoustic influences. The sounds of animal life—organisms from microscopic to huge—and those from the nonbiological landscape dominate the rather modest noises humans generate. They have limited language skills to express what they feel, but they borrow some from what they hear all around them to convey emotion. Perhaps, through their body movement and vocal responses—so evocative of the successful life heard everywhere—these modern humans will convince the other creatures that they are all just an extension of one sonorant family.

This is the tuning of the great animal orchestra, a revelation of the acoustic harmony of the wild, the planet's deeply connected expression of natural sounds and rhythm. It is the baseline for what we hear in today's remaining wild places, and it is likely that the origins of every piece of music we enjoy and word we speak come, at some point, from this collective voice. At one time there was no other acoustic inspiration.

CHAPTER ONE

Sound as My Mentor

Recording late one night deep in the Amazon jungle, my colleague Ruth Happel and I were alone in the forest several kilometers from camp with no light apart from the beams of our flashlights. Hoping to record the night ambience at several locations, we walked the trail quite aware of the tapestry of sounds around us. Along the way, we also picked up the unmistakable marking scent of a nearby jaguar. We never saw or heard the animal, but we knew it was close, perhaps even just a few feet away; it was frequently scent-marking as it followed us.

The musky feline odor was a constant presence. Our senses were heightened, but neither of us was afraid or perceived any immediate danger. Sitting quietly about fifty meters apart, we recorded the acoustic texture of the nighttime rain forest—the delicate admixture of raindrops on leaves, and insects, birds, frogs, and mammals performing their unified chorus as they have each day and night since the beginning.

After about an hour, we packed our gear and hiked deeper into the forest, listening for recording sites with more varied combinations. Then, around midnight, we decided to split up in order to gather the even greater variety of night sounds we hoped to encounter in this wonderfully rich environment. Ruth went down the path in one direction, and I went off in another.

After trekking for about fifteen minutes, I sat down beside the trail and began to record the intense tropical choruses of frogs, insects, and reptiles. Only then did I hear the cat's low growl in my headphones. It must have singled me out and followed me. Because I had the headphones' volume turned up to catch the fragile acoustic composition and detail of the forest, I wasn't attuned to my unlikely visitor—or aware that it had come that close. The sudden register of the jaguar's growls in my headset indicated that the cat was not more than an arm's length from the mics I had set up about thirty feet down the trail.

Fully alert in an instant, a rush of adrenaline catching me off guard, I felt my chest convulse. Trying to think of an exit strategy—there was none—I made some effort to calm down. In the moment, I thought that the sound of my heart was so audible, it would startle the animal. But I kept absolutely still, holding my breath in the darkness.

The incident lasted no more than a minute, but it seemed like a couple of hours as I sat mesmerized by the power of the animal's voice, its breathing, and the sounds of rumbles in its stomach. Then, as suddenly as it appeared, the jaguar moved silently off into the forest, leaving behind rhythmic waves of frog and whirring insect choruses, and what remained of my pounding heart.

It was by a happy accident that I was drawn to natural sound. My first career was as a studio guitarist, playing sessions of all kinds in Boston and New York. Then, in the mid-1960s, when musicians began experimenting with synthesizers, I moved to California to audit electronic music sessions at Mills College, where I met Paul Beaver, a Los Angeles studio musician and concert pipe organist who had made a career out of creating weird sound effects for feature films such as Creature from the Black Lagoon and War of the Worlds.

The wondrous-sounding tools of Paul's special trade were early synthesizer-like instruments such as the Ondes Martenot, the Hammond Novachord, and the Theremin, which produced an eerie, wavering soprano-like voice, and his own inventions, including an archetypal two-octave keyboard synthesizer that generated high-pitched sci-fi effects—he called it the "Canary." We immediately found creative synergy and formed the duo Beaver and Krause, and together introduced the synthesizer to pop music and film in California and the United Kingdom, produced five albums of our own, and performed music and effects for many features—including Rosemary's Baby, Apocalypse Now, Invasion of the Body Snatchers, and Performance— and on TV shows such as Mission: Impossible, The Twilight Zone, and Bewitched. We were so busy working one session after the other—sometimes as many as eighty hours a week—that the only recording date I clearly remember is one with the Doors on Strange Days. Early in the session the music was tight and energetic. As time passed over the course of a very long evening, the tracks became more fragmented and seemed to fall apart. When I finally realized that the deterioration wasn't the result of fatigue, I vowed never to touch another drug. The year: 1967.

Paul and I were commissioned to do a series of albums for Warner Brothers in 1968. The first, titled In a Wild Sanctuary, would be the earliest musical piece to use long segments of wild sound as components of orchestration, and also the first to feature ecology as its theme. But being first meant that we had to collect the sounds ourselves. Wary of shedding his blue serge double-breasted suit and wing tips—his daily costume even in the most stifling L.A. weather—Paul refused to head into the field, leaving the task to me.

The writer Thomas Hardy spoke of chance encounters that alter the course of our lives. A chance meeting with another person. A missed or unread letter. The vivid colors in a sunset. A musical performance. This first venture was bursting with the possibility of such a Hardyesque chance, and I set off, with a compact portable recorder and a pair of mics, to record in and around San Francisco, my home at the time.

In October there was not much birdsong in the area—most birds had fledged, had migrated, or were silent. Nevertheless, the instant I switched on my recorder in resplendent Muir Woods one lovely fall day in 1968, my acoustic sensibilities were transformed by the ambient space that enveloped me. The summer fog was at long last gone, and shafts of dappled fall sunlight perforated the canopy of the old-growth coastal redwoods. Except for a few small aircraft and an occasional distant automobile, the muted ambience heard throughout the woods—a constant reassuring whisper—came from a soft breeze in the upper reaches of the forest. Though I was at first quite afraid of being alone—even in a managed forest like Muir Woods—stillness overcame and calmed me.

Like a pair of binoculars, my mics and earphones brought the sound within a close and intimate range, exposing a range of vivid detail that was entirely new to me. A few birds flew overhead through the stereo space—right to left—the slow cadenced edge-tones of their undulating wings a diaphanous mix of whirr and shush. With my portable recording system, I didn't feel like I was listening as a distant observer; rather, I had been sucked into a new space—becoming an integral part of the experience itself. It was one of those moments you run toward and fully embrace with an open spirit, afraid it might not last and knowing you've experienced something you will always crave.

Sitting alone on the ground with my recorder, trying to appear small and unobtrusive, I was startled by each new sound. Many of the subtle acoustic textures around me were made larger than life through my stereo headphones, on which I cranked the monitor levels so that I wouldn't miss anything. The impact was immediate and forceful. Impressions of lightness and space were alluring and lustrous. The ambience was transformed into minute detail that I would have never caught with my ears alone—the sounds of my breathing; the slight movement of a foot adjusted into a more comfortable position; a sniffle; a bird landing nearby on the ground, stirring up leaves and then pushing air with its wing beats in short, quick puffs as it took off, alarmed.

I realized, even then, that wild sound might contain huge stores of valuable information just waiting to be unraveled. But to that point in my life, I'd had no way of understanding that the natural world was filled with so much wondrous chatter. How was anyone to know? Many of us don't distinguish between the acts of listening and hearing. It's one thing to hear passively, but quite another to be able to listen, fully and actively engaged.

My ears indifferently heard sound, but they weren't trained to distinguish the many subtleties of untamed natural environments. I had always used my ears as filters—for shutting noise out—rather than as portals allowing large amounts of information in. A fine microphone system lets me differentiate between what to listen to and what to listen for. Through headphones, I hear pieces of the aural fabric in such gloriously clear detail that I am still surprised by how much I was previously missing. A pair of stereo microphones transforms the acoustic space—when I turn up the volume slightly above what I can hear unaided, I get an "out of this world" impression that I imagine astronomers might feel when they receive Hubble telescope images of exploding supernovas from the far reaches of the universe.

Dorothea Lange, the Depression-era American photojournalist, used to say that a camera is a tool for learning to see without a camera. Well, a recorder is a tool for learning to listen without a recorder. The instant I first heard a spring dawn chorus, finally limning the visual setting with a proper sound track amplified through headphones, I immediately realized that with my unfocused ears I had been missing an exquisite part of real-world experience. Amplified sound gave me a way to decipher the language of the wild in ways my musically trained, "cultured" listening couldn't otherwise grasp. Sitting there recording, I often felt a sudden urge to join the performance. And a feeling of incompleteness nagged at me as I left the forest that day. It was a combination of important secrets left unspoken or unheard and a sense of having lucked into a path of discovery that was nothing short of a divine revelation.

While working on our fifth title, an updated version of an earlier hit for Nonesuch Records, Paul collapsed onstage during a concert in Los Angeles in January 1975. He died a day later from a brain aneurysm. Heartbroken by the loss of my good friend and music partner, I completed the album (Citadels of Mystery) with a group of musicians that featured Andy Narell and other studio friends. And at that point I began to rethink my career choices. In my mind, the last truly productive period in the record industry had passed. Ever more tired of the vagaries and egos of Hollywood—I had been fired and rehired more than half a dozen times during the making of Apocalypse Now alone—I decided to make a change. At forty years old, I quit the music world that I had always known and enrolled in a graduate studies program, earning a doctorate in creative arts with an internship in marine bioacoustics.

You might think I left the world of music behind for that of natural sound. Instead, that is where I truly found it.

Without water, life as we know it wouldn't exist. Giving off the most ancient of sounds, it is extremely hard to capture acoustically and replicate. Its burbling, hissing, lapping, roaring, crashing, multi-rhythmic periodicity has served as a setting for human themes since the first music was sung and the first words spoken.

It took the full course of musical history for a composer to produce an orchestral composition that approximated a sense of the sea—Debussy got close in La Mer, which was first performed in 1905. However, his piece still required that programmatic visual quality and verbal association in order to be reasonably successful. Here's an interesting exercise: play excerpts from the piece for a few people who've never heard the work and don't know the title, and ask them what they think it is trying to convey. The one time in the late '90s that I tried this test—playing the six-minute second movement ("Jeux de vagues") for a class of seventh graders—the answers ranged from "traveling in space," "music for a film about the country," "a scene about a family of dinosaurs," and "a Western movie" to "just plain boring." Not one student guessed that the music represented an impression of the sea or even water.

At first glance, the task of recording water looks simple: set up a microphone by the shore and hit the "record" button. But no matter how hard I tried, my early attempts at capturing the sound of water never seemed quite right. We're so sight-oriented that most of us who have reasonable vision tend to hear what we are looking at. When we're focusing our eyes on breakers far offshore, our ears and brains usually filter out all but the boom and crash of waves that suggest distance and incredible force. When we're staring at the leading edge of the waves as they wash up the rake of the beach, we hear the tiny bubbles crackling and snapping as they rupture in the sand at our feet, while the sounds of the distant breakers fade into the background.

Microphones, however, don't have eyes or brains. They indiscriminately pick up everything within the scope of their design. So, I discovered, if I want to portray the sound of an ocean shore, I need to record a variety of samples from different distances: a couple of hundred feet from the water's edge, mid-distance from the high dune grasses to the water's edge, and right at the waterline. By using sound-editing software to combine all the samples at various levels when I get back home, I am able to capture audio that sounds very much like the magic of waves at the ocean. But in its most granular form, what exactly is it that I'm recording? What is sound?

Sound is a medium that's hard to describe beyond its physical properties—frequency, amplitude, timbre, and duration. Yet it plays a key role in the ways societies express themselves; it is fundamental to the collective voice of the natural world, to music, and to acoustic noises of all kinds.
