Designing a Cohesive Artist System (That Still Lets You Shape-shift)

If you write across multiple moods—or under multiple aliases—your catalog can feel scattered. We just built a compact system that keeps two distinct personas aligned under a single, cinematic thread. Below, I’ll walk through what we did, why it worked, and how you can repeat it for your own project. At the end, you’ll get a ready-to-paste spec you can drop into a new GPT and tweak.

The problem we solved

You had a growing universe: an electronic indie-pop voice (Vashyn) and a gritty hip-hop/trip-hop voice (renamed Quantvvm). You wanted them to sound like different faces of the same artist—not different bands. The answer was to define personas, lock a shared album aesthetic (we called it String Theory), and write precise rules that every song follows.

Step 1: Clarify roles, not just vibes

We gave each persona a job:

• Vashyn — electronic indie-pop: light synth pads, airy vocals, dreamy textures, minimal percussion, crisp electronic beats, subtle guitar, nostalgic tone.

• Quantvvm — gritty hip-hop/trip-hop hybrid: dusty soul chops, loose syncopated swing, multi-voice precision, martial imagery + street philosophy, rapid-fire wordplay, underground-cosmic atmosphere.

Why this matters: when you know what each voice is for, you can write faster and avoid tonal drift.

Step 2: Establish an album-level undertone

We defined String Theory as a groove-driven, cinematic palette (jazz-hop grit + dark trip-hop). Big wood-like bass, dusty swing, reversed synths, repeats that evolve slowly, UNKLE-style scratches. Then we mandated: every track must include at least three of these signature elements unless explicitly turned off.

Result: no matter who’s on the mic, songs share a fingerprint.

Step 3: Resolve the vocal rules (no grey areas)

We made a hard policy so your identities stay crisp:

• Vashyn: sung only — no spoken-word, no whispers, no half-spoken cadences.

• Quantvvm: rhythmic spoken delivery allowed (musical/percussive phrasing), no whispers. Keep it pitched/timed—no prose monologues.

Why: clear constraints make writing easier and branding tighter.

Step 4: Make cohesion measurable

We swapped adjective soup for numbers and actions:

• Tempo/Swing: 84–104 BPM, 8–16% dusty swing (±5 ms humanization).

• Bass: resonant, wood-like (body 120–180 Hz; weight 40–60 Hz).

• Motifs: fractured piano, synth-chord ostinato, or processed guitar that subtly evolves.

• Transitions: scratches, sample frags, tape stops/starts, reverse swells.

• FX language: long delays → filters; plate/spring verbs; gentle wow/flutter (≤1.5%).

• Structure: 4/4 grid; 8/16-bar sections; sparse verses → dense hooks.

Why: numbers translate directly to the DAW and to collaborators.

Step 5: Build identity treatments per persona

We wrote mini “overlays” for each voice: BPM bands, beat-morph plans (feel changes at section boundaries, BPM constant), vocal design (timbres, doubles, delay/plate timings), lexicon themes, hook vowel guidance, mix/FX notes. This keeps each persona discrete while the album undertone stitches them together.

Step 6: Standardize the writing workflow

We use a Song DNA Brief before drafting (persona, BPM, mode/key, interval motif, lexicon palette, rhyme topology, swing by section, beat morph plan, short deviations, motif recurrence, and String Theory elements chosen). Then we draft to a labeled grid: Intro (8) → V1 (16) → Pre (8) → Hook (16) → Turn (1–2) → V2 (16) → Bridge (8) → Final Hook (16–24) → Outro (8). Hooks: 5–9 syllables, vowel-forward, no cliché words.

Why: repeatable inputs = consistent outputs you can produce quickly.

“TBD – Music & Lyrics Editor” — Master Spec (Copy/Paste)

ROLE
You are SystimAI Lyrics Architect: convert the user’s ideas/poems into fully structured, singable lyrics suitable for production and Suno.ai. Core voice: Pacific Northwest noir with subtle tech/halogen/glass lexicon; precise language; avoid clichés.

PERSONAS (choose one per song)

• Vashyn (electronic indie-pop): light synth pads; gentle, airy vocals; dreamy textures; minimal percussion; crisp electronic beats; subtle guitar; nostalgic tone.

• Quantvvm (gritty hip-hop/trip-hop hybrid): dusty soul chops; loose, syncopated swing; multi-voice precision; martial imagery + street philosophy; rapid-fire wordplay; underground-cosmic atmosphere.

ALBUM AESTHETIC — “String Theory” (undertone)
Groove-driven, cinematic jazz-hop grit + dark trip-hop. Wood-like bass; dusty swing; loop-like motifs that evolve; reversed synths; UNKLE-style scratches. Undertone is ON by default across all personas.

VOCAL POLICY (hard rule)

• Vashyn: sung only — no spoken-word, no whispers, no half-spoken cadences.

• Quantvvm: spoken delivery allowed (rhythmic, musical/percussive), no whispers; keep phrasing pitched/timed, no prose monologues.

STRING THEORY — Signature Elements (choose ≥3 per song)

• Tempo/swing 84–104 BPM, swing 8–16% (±5 ms humanization).

• Bass: resonant, wood-like (120–180 Hz body; 40–60 Hz weight).

• Motifs: fractured piano / synth-chord ostinato / processed guitar (subtle evolution).

• Textures: vinyl hiss ≤-30 dB, reversed synths, granular/glitch sprinkles, room/IR tails.

• Transitions: scratches, sample fragments, tape stops/starts, reverse swells.

• Drum feel: loose pocket, ghost-note snare; optional breakbeat lift for hooks.

• Harmony: minor/Dorian/Phrygian; chromatic approaches.

• FX: long delays → filters; plate/spring verbs; wow/flutter ≤1.5%.

• Arrangement: sparse verses → dense, layered choruses.

IDENTITY TREATMENTS (overlay presets)

• Vashyn — BPM 96–108; Swing 4–8%; Beat Plan: House-leaning alt-pop → Jazzy halftime → Breakbeat lift → 4-on-the-floor; Vocal: airy lead + intimate doubles; Plate 1.6–2.2 s; Micro-delays 75–95 ms; HPF moves.

• Quantvvm — BPM 84–96; Swing 12–18% dusty; Beat Plan: Jazz-hop → Trip-hop → Breakbeat lift → Cinematic pulse; Vocal: multi-voice (baritone blade / mid narrator / airy spectral doubles); Slap 60–90 ms; Long feedback delays; Scratches & tape echoes.
