TECHNICAL DOCUMENTATION
How SHE works.
An overview of how SHE is built, what it draws on, what it returns, and how a piece comes together. For teams looking at SHE for their product.
HOW IT'S BUILT
Four layers, from theory to finished piece.
People built every part. SHE did not train a model — experts wrote the rules. It 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. The universal layer beneath any genre.
Library — the catalogs
Chord patterns, rhythms, styles, moods, and instruments, each one drawn from tradition, validated, and organized. Labels like "Soul" or "Uplifting" map to specific, tested behavior — not a prompt interpretation.
Orchestration — the composers
Where the music takes shape: choosing the chords, shaping the bass, writing the melody, planning the sections, and setting the energy. Each part is written aware of the rest.
Export — assembly & handoff
Putting it together and handing it off: the audio, the editable arrangement, the description, and the record, all at once.
SETTING THE SPACE
SHE works within whatever space it is given.
A handful of settings narrow where SHE composes. Use as many or as few as the job needs. With none set, it ranges freely. The same settings and the same ID return the same piece, on any machine.
Genre
The musical tradition to work in. Each one is tuned by hand to sound like itself, shaping rhythm, instrument choice, and harmonic style.
House, Jazz, Electronic, Soul, Ambient, Hip-Hop
Mood
The emotional color: bright or dark, calm or intense, sparse or full. Moods can be combined.
Energetic, Melancholic, Uplifting, Dark, Peaceful
Key
The home note for the whole piece. Everything settles around it.
Any of the 12 musical keys
Scale
The overall character, brighter or darker. SHE fits every note to it.
Major, Minor, Dorian, Mixolydian, and more
Chords
A chosen progression, or one SHE picks to suit the genre and mood. Each progression carries its formula and harmonic role.
I–V–vi–IV, ii–V–I, vi–IV–I–V
Tempo
The speed, in beats per minute. It carries the feel and the energy.
60–200 BPM (default: 120)
Song Form
The shape of the song: which sections appear, in what order, and how long. Each section has its own energy.
Full (intro–verse–chorus–bridge–outro), Loop, Verse-Chorus
WHAT IT RETURNS
Four outputs, made together.
Each piece returns four things from the one pass. No cleanup, nothing to reverse-engineer.
- Full mix and individual stems (chords, bass, melody, drums, pad)
- WAV, 44.1 kHz sample rate
- Ready for playback, production, or direct integration
- The note-by-note instruction layer — every note and instrument
- 480 ticks per beat resolution
- Separate tracks per instrument role, with velocity and timing
- Opens in any music production software
- Key, tempo, scale, and time signature
- Chords with per-section harmonic rhythm
- Section markers with bar counts and energy
- Instrument roles per section — written as the music is made, not inferred
- A complete record of every choice SHE made, and why
- Machine-readable, paired with the audio for training and labeling
- The progression, the form, and the ID to rebuild the exact piece
- Full provenance on every piece
HOW A PIECE COMES TOGETHER
From a space to finished music.
A single piece runs through five steps. Each one is logged and traceable.
Define
Set genre, mood, key, scale, tempo, and form — or leave it open.
Select
SHE picks the chords, instruments, and rhythmic feel that fit, and notes why.
Compose
It writes the bass, melody, chords, drums, and pad — each part aware of the others.
Arrange
It shapes the sections: energy, transitions, and density across the piece.
Export
Audio, arrangement, description, and record are produced together. Every file is labeled and traceable.
System requirements: SHE runs on ordinary hardware, including low-power devices. No GPU, no cloud required. The same request returns the same piece, on any machine.
API ACCESS
Build SHE into your product.
The SHE API takes a request and returns the full package — audio, the editable arrangement, a description, and a complete record — in a single response, or opens a live stream.
Request
Send your settings — genre, mood, key, scale, tempo, form — and SHE composes a complete piece.
genre: "electronic"
mood: "energetic"
key: "C", scale: "dorian"
tempo: 128
form: "full"
id: 1311 // optional. omit and SHE chooses.
Response
Receive the full package: the audio, the editable arrangement, a description, and a complete record of every decision.
audio: [full_mix.wav, stems/...]
parts: [chords.mid, bass.mid, ...]
description: {key, tempo, scale, ...}
record: {chords, choices, id, ...}
Authentication
API access is granted per organization. Each partner receives dedicated credentials and limits set for their use case.
Output formats
WAV audio, standard MIDI, and a machine-readable description and record. Delivered together per piece, or streamed live.
Local deployment
SHE can run entirely on a partner's own hardware. No GPU required; standard, low-power devices are enough to run.
