Master the three fundamental vocabularies for AI music: Mood Tokens, Texture & Production Descriptors, and Structural Dynamics. Includes cross-reference tables and negative prompt exclusion techniques.
YuE2 Music Research LabIn prompt engineering for neural music diffusion models, vocabulary choice dictates acoustic output quality. This guide catalogs the three most vital descriptor systems: Mood Tokens, Texture & Production Descriptors, and Structural Dynamic Markers, complete with use-case scenarios and negative exclusion methods.

1. Mood Tokens
Mood tokens specify the emotional baseline and psychological atmosphere of the piece.
| Keyword | Definition | Optimal Genres & Context | | :--- | :--- | :--- | | Cheerful / Joyful | Happy, lighthearted | Upbeat pop, celebration anthems, festive themes | | Melancholic / Somber | Sorrowful, deep, heavy | Slow ballads, solo cello & piano, late-night introspective tracks | | Bittersweet | Sweet yet sorrowful | Nostalgic memoirs, indie pop, graduation anthems | | Nostalgic | Wistful, retro-tinged | Lo-fi, 80s Synthwave, City Pop, cassette tape aesthetics | | Dark / Ominous | Menacing, shadowy | Heavy metal, Trap, Drill, cinematic villain themes | | Bright / Uplifting | Radiant, inspiring | Sunny pop, Gospel choirs, motivational anthems | | Epic / Cinematic | Grand, monumental | Large orchestra, game battle OSTs, trailer backdrops | | Intimate / Personal | Close-mic, vulnerable | Bedroom Pop, acoustic folk, whispered vocals | | Euphoric | Pure bliss, ecstatic | EDM, Progressive House, festival anthems | | Haunting | Unsettling, lingering | Ambient, Post-rock, experimental dark electronics | | Triumphant | Victorious, heroic | Epic brass fanfare, sports stadium anthems, rock climaxes | | Dreamy / Ethereal | Otherworldly, floating | Shoegaze, Chillwave, Xianxia / Guofeng fantasy | | Aggressive / Fierce | High-intensity, intense | Metalcore, Punk rock, high-octane workout beats | | Serene / Peaceful | Calm, meditative | Nature ambiance, neoclassical piano, mindfulness music | | Playful / Whimsical | Quirky, imaginative | J-Pop, anime themes, playful indie pop | | Groovy | Rhythmic, body-moving | Funk, Disco, Modern R&B, dancefloor basslines | | Tense / Suspenseful | Anxious, dramatic | Film thrillers, mystery soundtracks, chase scenes |
Stacking Rule: Multiple mood tokens synergize well (e.g.,
bittersweet, nostalgicordreamy, melancholic). However, never combine diametrically opposed moods likeaggressiveandpeaceful, as this fractures model attention weights.
2. Texture & Production Words
These descriptors control physical audio characteristics, production era, and recording environment.
| Keyword | Definition | Acoustic Texture & Application | | :--- | :--- | :--- | | Raw | Unprocessed, visceral | Captures live garage room imperfections; garage rock, live folk | | Polished | Sleek, commercial | Studio-grade multi-track mastering, pristine balance | | Analog / Vintage | Warm, tape-saturated | 70s-80s hardware tube warmth, rich mid-low punch | | Digital / Clean | Ultra-clear, bright | Modern crisp high frequencies; EDM, Future Bass, K-Pop | | Warm | Full-bodied, inviting | Round low-mids, soothing bass; Neo-Soul, Lo-fi | | Cold / Icy | Distant, clinical | Sharp highs, metallic bite; Industrial Techno, winter OSTs | | Lo-fi | Low fidelity charm | Intentional tape hiss, vinyl dust, warm flutter | | Hi-fi | High fidelity fidelity | Audiophile transparency, rich overtone capture; Classical, Jazz | | Distorted | Overdriven, clipped | Tube clipping, fuzzy buzz; Rock, Metal, Industrial | | Reverb-heavy | Vast, cathedral space | Huge hall decay; Shoegaze, Post-rock, ethereal ambient | | Dry | Up-close, no reflections | In-your-ear clarity; tight drums, funk slap bass, upfront rap | | Atmospheric | Swelling soundscapes | Shimmering synth pads; Ambient, Post-rock | | Gritty | Sandy, textured | Grimy tactile grain; Delta Blues, Garage Rock | | Lush | Sumptuous, opulent | Thick orchestral layers, wall of sound pop production | | Sparse / Minimal | Stripped back, spacious | Strategic silence and breath; Neoclassical, intimate folk | | Crisp | Snappy, articulated | Fast transient attack on drums and plucks; modern dance |
3. Structure & Dynamic Tokens
Dictate the kinetic trajectory and energy distribution of the composition.
- Catchy chorus / Strong hook: Creates an irresistible melodic centerpiece.
- Build-up and drop: Tension buildup followed by sudden bass release; fundamental for electronic dance music.
- Steady groove: Rhythmic consistency; indispensable for Funk, R&B, and Soul.
- Dynamic contrast (soft-loud): Pronounced shifts between gentle verses and thunderous choruses.
- Layered arrangement: Distinct instrumental counter-melodies across a wide stereo field.
- Stripped-down / Acoustic: Unplugged intimacy, shedding synthetic elements.
- Call-and-response: Antiphonal dialogue between lead vocal and choir/lead instruments.
- Progressive / Evolving: Linear narrative progression with no static looping.
4. The Exclusion Method (Negative Prompts)
In prompt craft, declaring what you do NOT want is often faster and cleaner than stacking ten positive adjectives.
Essential Negative Exclusion Tokens:
no vocals / instrumental: Disables singing entirely, guaranteeing pure instrumental music.no autotune: Removes digital pitch correction, preserving organic vocal timbre.no drums: Strips out all percussion for serene contemplation.no heavy reverb: Eliminates cavernous room echoes for crisp intimacy.purely acoustic / no electronic elements: Prevents synths and samplers from intruding.no distortion: Ensures squeaky-clean guitar and vocal signals.no rap: Excludes spoken-word verses in favor of soaring melodic singing.
Exclusion Guideline: Limit negative exclusions to 2 or 3 tokens. First describe your target aesthetic, then prune unwanted artifacts with negative tags.
