Permanent Exhibition

The Sound of the Machines

Constraints gave music its character.

This music was not performed. It was calculated.

A game composer in 1990 did not sit at a piano and play. They wrote numbers — which channel, which frequency, for how long, how loud — and fed those numbers to a machine that had never heard music before and had no opinion about what it was supposed to sound like. The Famicom gave them five simultaneous sounds to work with. The Game Boy gave them four. The entire emotional range of an adventure, a boss fight, a town at peace, a moment of triumph — all of it had to fit inside those limits. Not as a style choice. As an absolute physical fact.

What happened inside those limits is this exhibition.

Each machine here had a sound chip with its own specific constraints — not just in the number of channels, but in the waveforms available, the memory budget, the quirks of how the hardware worked in practice. Those constraints were not obstacles that great composers worked around. They were the conditions inside which music was invented. The triangle wave became a bass instrument because there was no bass instrument. A chip's design flaw became a signature sound because composers heard something in the distortion that they decided to keep. Sixty-four kilobytes of memory gave Super Famicom music its characteristic warmth, because compression rounds off high frequencies and warmth is what is left.

Each piece in this exhibition was composed by Tomita, Enjoy Game Japan's in-house composer. Every track begins with a real fact about the hardware — a constraint, a quirk, sometimes a flaw — and asks: what music would you write if that were the only truth you had to work with? Tomita's answer is what you hear when you press play. His account of how the limit shaped the music is what you read on each machine's page.

Press play first. Read what was happening underneath afterward. The order matters.

Eight Machines. Eight Constraints. Eight Pieces.

Ricoh 2A03 5 channels

Famicom / NES

Track: A Song of Ma — The Art of Silence

The bass channel had no volume knob. Only on or off.

Tomita: "The triangle wave cannot whisper. So I learned to speak in silence."

Sony SPC700 8 channels

Super Famicom / SNES

Track: The Forbidden Challenge

This chip was designed in secret. The engineer was reprimanded. Then he went on to create the PlayStation.

Tomita: "I started alone, with a single piano. At bar 8, the brass entered — everything that had been building in silence arrived at once."

Yamaha YM2612 + SN76489 10 channels (FM + PSG)

Mega Drive / Genesis

Track: Song of the Ladder

A design flaw added grit to quiet sounds. Composers wrote around it. When Sega fixed the bug, the music sounded wrong.

Tomita: "There was a bug in the chip. I made it the lead voice."

DMG-CPU (built-in APU) 4 channels

Game Boy

Track: Miracle of Four Voices

Four channels cannot play a chord — mathematically impossible. So composers invented a trick to fool the ear.

Tomita: "One channel. Three notes, cycling faster than your ear can follow. You hear a chord that does not technically exist."

Hudson Soft HuC6280 6 channels

PC Engine / TurboGrafx-16

Track: Dawn Over the Fields

Every channel holds a custom waveform — you design the instrument from scratch.

Tomita: "Six blank canvases. I decided each one could only open when the story needed it."

Sony SPU (CXD2922) 24 voices

PlayStation

Track: Morning of Triumph

Twenty-four voices, but only one reverb for all of them — and that is the orchestra.

Tomita: "There is one reverb on the whole machine. I put all twenty-four voices in it, and they became an orchestra."

Yamaha SCSP (YMF292) 32 voices

Sega Saturn

Track: Corridor of Night

More powerful than the PlayStation, and harder to use. The difficulty was the character.

Tomita: "The Saturn would not hand me warmth. It handed me control, and made me build the room myself."

Enter this exhibition →
Yamaha YM2610 15 channels (FM + SSG + ADPCM)

Neo Geo

Track: Iron Dawn

The famous aggression is not distortion. It is detuning — precision in a costume.

Tomita: "I thought the bite was distortion. The real registers said it was two voices a cent apart."

Why does this exhibition exist?

Because what happened inside those limits deserves to be seen, not just heard.

Most people who grew up with Famicom or Game Boy music carry it with them — the specific sound of a particular game at a particular moment in their life. That sound has an explanation. The reason the Famicom sounds the way it does, the reason the triangle wave bass has that particular quality, the reason Super Famicom music has warmth and Mega Drive music has grit — all of that is the consequence of specific hardware decisions made by specific engineers, often under pressure, for reasons that had nothing to do with art. Art happened anyway.

This exhibition makes that process visible. Not to explain the feeling away — but to show that the feeling came from somewhere real. A specific limitation produced a specific sound. That sound became a memory. That memory is why you are here.

About the Composer

Tomita is the in-house composer for Enjoy Game Japan Museum. All tracks in this exhibition are original works — not covers, not arrangements, not tributes to existing games. They are new pieces, composed specifically for this exhibition, on the original hardware constraints of each machine.

Each composition begins with a piece of trivia: a real historical fact about the sound chip — a constraint, a technical quirk, sometimes a design flaw — and then asks: what music would honestly live inside that fact? Tomita's answer is what you hear when you press play. His account of the process — what he chose, what the chip forced him to choose, what he discovered along the way — is what you find on each machine's page.

Origin Pieces — Inspired By the Masters

Four original compositions, each sparked by a single question: what emotional truth made that piece of music survive for decades? The melodies are entirely new. Only the feeling — the chip, the era, the constraint — carries over.

PS1 SPU · E minor · BPM 72

Memory of Aeris

Warmth of Memory

Nobuo Uematsu said he "did not write it to make people cry." It is sad, yet it never accuses you — less a sound of loss than a quiet tenderness.

SFC SPC700 · C major · BPM 88

The Sea of Beginnings

Rising Drops

Nobuo Uematsu is said to have written the "Prelude" in ten minutes. A rising arpeggio, like water running over glass. The beginning of every journey.

SFC SPC700 · A minor · BPM 84 · 6/8

Corridor of Time

Stepping into Eternity

Yasunori Mitsuda wrote it while hospitalized with a stomach ulcer. Out of that exhaustion came "the feeling of stepping into eternity" — a stillness where time stops, a corridor that loops and returns.

NES 2A03 · G major · BPM 130

Dream of the Land

A Hero Born in One Night

Koji Kondo wrote "the Zelda main theme" in a single night. A forward-marching momentum, a rising lift, a melody that stays with you — a brass band in four Famicom voices.

SFC SPC700 · G major · BPM 80

Beyond the Resolve

Heroic yet Tender

On the Super Famicom, the echo settings could not be changed midway through a piece. So I placed the whole journey inside a single space, from first note to last. It opens with a perfect-fifth leap, G4 to D5; at 15 seconds it shifts to A minor as the horns settle in; at 24 seconds it reaches its peak on G5; and from 30 seconds it fades away.

NES 2A03 · D minor · BPM 130 · Texture

Breath of the Star

Music That Does Not Comfort

Hirokazu Tanaka left out the melody — "so that only the victor would feel the catharsis." This piece has no melody. There is only a pulse, a phrase that never resolves, and the breathing of a planet.

All melodies are original — no existing game music is reproduced. Only the chip, the era, and the emotional constraint are carried over.
