But at 50,000 dollars each they also represented a terrifying hazard to the clumsy sound-sweep. Only two years earlier the entire north transept of Rheims Cathedral, rose window intact, purchased for a record 1,000,000 dollars and reerected in the new Cathedral of St. Joseph at San Diego, had been drained of its priceless heritage of tonal inlays by a squad of illiterate sound-sweeps who had misread their instructions and accidentally swept the wrong wall.
Even the most conscientious sound-sweep was limited by his skill, and Mangon, with his auditory supersensitivity, was greatly in demand for his ability to sweep selectively, draining from the walls of the Oratory all extraneous and discordant noises—coughing, crying, the clatter of coins and mumble of prayer—leaving behind the chorales and liturgical chants which enhanced their devotional overtones. His skill alone would lengthen the life of the Assisi pediments by twenty years; without him they would soon become contaminated by the miscellaneous traffic of the congregation. Consequently he had no fears that the Dean would complain if he failed to appear as usual that morning.
Halfway along the north side of the park he swung off into the forecourt of a huge forty-story apartment block, a glittering white cliff ribbed by jutting balconies. Most of the apartments were Superlux duplexes occupied by show business people. No one was about, but as Mangon entered the hallway, sonovac in one hand, the marble walls and columns buzzed softly with the echoing chatter of guests leaving parties four or five hours earlier.
In the elevator the residues were clearer—confident male tones, the sharp wheedling of querulous wives, soft negatives of amatory blondes, punctuated by countless repetitions of “dahling.” Mangon ignored the echoes, which were almost inaudible, a dim insect hum. He grinned to himself as he rode up to the penthouse apartment; if Madame Gioconda had known his destination she would have strangled him on the spot.
Ray Alto, doyen of the ultrasonic composers and the man more than any other responsible for Madame Gioconda’s decline, was one of Mangon’s regular calls. Usually Mangon swept his apartment once a week, calling at three in the afternoon. Today, however, he wanted to make sure of finding Alto before he left for Video City, where he was a director of program music.
The houseboy let him in. He crossed the hall and made his way down the black glass staircase into the sunken lounge. Wide studio windows revealed an elegant panorama of park and midtown skyscrapers.
A white-slacked young man sitting on one of the long slab sofas—Paul Merrill, Alto’s arranger—waved him back.
“Mangon, hold on to your dive breaks. I’m really on reheat this morning.” He twirled the ultrasonic trumpet he was playing, a tangle of stops and valves from which half a dozen leads trailed off across the cushions to a cathode tube and tone generator at the other end of the sofa.
Mangon sat down quietly and Merrill clamped the mouthpiece to his lips. Watching the ray tube intently, where he could check the shape of the ultrasonic notes, he launched into a brisk allegretto sequence, then quickened and flicked out a series of brilliant arpeggios, stripping off high P and Q notes that danced across the cathode screen like frantic eels, fantastic glissandos that raced up twenty octaves in as many seconds, each note distinct and symmetrically exact, tripping off the tone generator in turn so that escalators of electronic chords interweaved the original scale, a multichannel melodic stream that crowded the cathode screen with exquisite, flickering patterns. The whole thing was inaudible, but the air around Mangon felt vibrant and accelerated, charged with gaiety and sparkle, and he applauded generously when Merrill threw off a final dashing riff.
“Flight of the Bumble Bee,” Merrill told him. He tossed the trumpet aside and switched off the cathode tube. He lay back and savored the glistening air for a moment. “Well, how are things?”
Just then the door from one of the bedrooms opened and Ray Alto appeared, a tall, thoughtful man of about forty, with thinning blond hair, wearing pale blue sunglasses over cool eyes.
“Hello, Mangon,” he said, running a hand over Mangon’s head. “You’re early today. Full program?” Mangon nodded. “Don’t let it get you down.” Alto picked a dictaphone off one of the end tables, carried it over to an armchair. “Noise, noise, noise—the greatest single disease-vector of civilization. The whole world’s rotting with it, yet all they can afford is a few people like Mangon fooling around with sonovacs. It’s hard to believe that only a few years ago people completely failed to realize that sound left any residues.”
“Are we any better?” Merrill asked. “This month’s Transonics claims that eventually unswept sonic resonances will build up to a critical point where they’ll literally start shaking buildings apart. The entire city will come down like Jericho.”
“Babel,” Alto corrected. “Okay, now, let’s shut up. We’ll be gone soon, Mangon. Buy him a drink would you, Paul.”
Merrill brought Mangon a Coke from the bar, then wandered off. Alto flipped on the dictaphone, began to speak steadily into it. “Memo 7: Betty, when does the copyright on Stravinsky lapse? Memo 8: Betty, file melody for projected nocturne: L, L sharp, BB, Y flat, Q, VT, L, L sharp. Memo 9: Paul, the bottom three octaves of the ultra-tuba are within the audible spectrum of the canine ear— Congrats on that SP of the Anvil Chorus last night; about three million dogs thought the roof had fallen in on them. Memo 10: Betty—” He broke off, put down the microphone. “Mangon, you look worried.”
Mangon, who had been lost in reverie, pulled himself together and shook his head.
“Working too hard?” Alto pressed. He scrutinized Mangon suspiciously. “Are you still sitting up all night with that Gioconda woman?”
Embarrassed, Mangon lowered his eyes. His relationship with Alto was, obliquely, almost as close as that with Madame Gioconda. Although Alto was brusque and often irritable with Mangon, he took a sincere interest in his welfare. Possibly Mangon’s muteness reminded him of the misanthropic motives behind his hatred of noise, made him feel indirectly responsible for the act of violence Mangon’s mother had committed. Also, one artist to another, he respected Mangon’s phenomenal auditory sensitivity.
“She’ll exhaust you, Mangon, believe me.” Alto knew how much the personal contact meant to Mangon and hesitated to be overcritical. “There’s nothing you can do for her. Offering her sympathy merely fans her hopes for a comeback. She hasn’t a chance.”
Mangon frowned, wrote quickly on his wrist-pad: She WILL sing again!
Alto read the note pensively. Then, in a harder voice, he said, “She’s using you for her own purposes, Mangon. At present you satisfy one whim of hers—the neurotic headaches and fantasy applause. God forbid what the next whim might be.”
She is a great artist.
“She was,” Alto pointed out. “No more, though, sad as it is. I’m afraid that the times change.”
Annoyed by this, Mangon gritted his teeth and tore off another sheet: Entertainment, perhaps. Art, no!
Alto accepted the rebuke silently; he reproved himself as much as Mangon did for selling out to Video City. In his four years there his output of original ultrasonic music consisted of little more than one nearly finished symphony— aptly titled Opus Zero—shortly to receive its first performance, a few nocturnes and one quartet. Most of his energies went into program music, prestige numbers for spectaculars and a mass of straight transcriptions of the classical repertoire. The last he particularly despised, fit work for Paul Merrill, but not for a responsible composer.
