SHE is the Structure.
Harmony is the Space.
Endless musical possibilities, grounded in theory, tuned by experts, emergent by design.
WHAT SHE IS
It writes music, produces the mix, and gives you a record of the process.
Think of SHE as both an instrument and composer.
It uses taxonomies (catalogs of genres, instruments, moods, rhythms) and rules (this pitch most likely comes after this pitch) to help the system know what to build.
MIDI. METADATA. AUDIO.
BUILT FROM MUSIC THEORY
Four layers, theory to finished piece.
SHE works from two kinds of knowledge, through four layers, each with one job.
Theory
The foundation: how music works. Intervals, harmony, rhythm, and meter, true across every style.
Library
The collections: chord patterns, rhythms, styles, moods, and instruments, each one drawn from tradition, validated, and organized.
Orchestration
Where the music takes shape: choosing the chords, shaping the bass, writing the melody, planning the sections, setting the energy.
Export
Putting it together and handing it off: the audio, the editable parts, the description, and the record, all at once.
People built every part. SHE doesn't need model training or audio to learn. That is why every output is original and traceable to the decision that made it.
MORE THAN AUDIO
Every layer, ready to use.
Each piece arrives as four things at once, with no guess-work, all understandable.
Audio
The finished music, as a full mix and as separate tracks for chords, bass, melody, drums, and pad.
Arrangement
Every note and instrument as MIDI — the note-by-note instruction layer — open in any music production software.
Descriptions
The key, tempo, chords, sections, and what each instrument plays, written as the music is made and built to be read by a machine as easily as by a person.
Decisions
Each choice SHE made, and the ID to call the exact piece back, note for note, on any machine.
SEE A COMPOSITION
One request. Four things at once.
Here is a single piece SHE composed, and everything it returns with it.
Audio
WAV · full mix + 5 stems
Editable MIDI
Note-by-note, every instrument — opens in any music production software.
A structured description
Key: "C", Scale: "dorian", Tempo: 128, Meter: "4/4", Progression: "i → IV → v → IV", Sections: [intro, verse, chorus, bridge, outro], Tracks: { chords, bass, melody, drums, pad }
Machine-readable — written as the music is made.
A complete record
Every decision SHE made — replay the ID to rebuild it exactly.
LIVE OUTPUT
NEWFiles, or a live stream.
SHE can hand back a finished package, or stream music live. It's continuous, original output that runs for as long as the product needs and never needs to repeat a song. Same engine, same hardware, no cloud required. It is the opposite of a fixed loop: the music keeps moving, and you can still call any second of it back exactly.
WHO BUILDS WITH SHE
For each context music needs to scale.
AI & Music Technology
Structured, labeled music data.
Teams training music models need data that is structured, labeled, and original: audio paired with the exact notes and structure behind it. SHE hands over the notes, the description, and the audio together, perfectly matched, so models learn from the structure, not just the sound. Every piece is original, with full provenance.
Gaming
Music that evolves with the player.
Game soundtracks have to grow across sessions, levels, and player states without wearing thin. SHE writes fresh music in a set style and never repeats a song. Stream it live for as long as a session runs, and find any moment again by its core ID.
Enterprise & Background Audio
On-brand music at any scale, live.
Stores, phone systems, and branded spaces need steady music that holds a feel without wearing thin. SHE streams original music live, on brand, for as long as the product runs — without ever settling into the handful of bars you hear on hold.
Music Education
Theory, heard and seen at once.
Theory lands when it can be heard and seen at the same time. SHE writes examples in any key, scale, or form, and lays the chords bare behind them.
ACCESS
Let's build something worth hearing.
Structured Harmony Engine is in private access. We work directly with teams that need music at scale.
