- **Choir** — multiple voices

## Vocal style descriptors

- Doubled — same vocalist recorded twice for thickness
- Call-and-response — vocal answers vocal

### Delivery style
- Smooth, controlled
- Raspy, gritty
- Whispered, intimate
- Belted, powerful
- Auto-tuned
- Melismatic (multiple notes per syllable)
- Rhythmic / staccato
- Sustained / legato

### Cultural styles

- Gospel — call-and-response, choir backing
- Operatic — vibrato, full voice
- Yodeling — switching head/chest voice
- Throat singing — multiple tones simultaneously

## Per-section vocal assignment

Common patterns:

### Single vocalist
Verse, chorus, bridge — same person throughout.

### Duet
- Verse 1: Person A
- Verse 2: Person B
- Chorus: Both together
- Bridge: Trade lines

### Multi-vocal
- Verse: Lead alone
- Pre-chorus: Backing harmonies enter
- Chorus: Full harmonies
- Bridge: Maybe just lead, or all together

### Lead + Choir
- Lead vocalist throughout
- Choir on chorus only (or bridge)

## Vocal effects

- Reverb (wet/dry) — adds space
- Delay — echo
- Auto-tune — pitch correction (subtle to extreme T-Pain)
- Vocoder — robotic
- Distortion — aggressive
- Doubling — thickness
- Octave doubling — power

## Examples (artist references)

- **Modern R&B** (The Weeknd) — male falsetto, smooth
- **Indie folk** (Bon Iver) — male falsetto, layered harmonies
- **Soul** (Adele) — female alto, powerful, melismatic
- **Country** (Chris Stapleton) — male baritone, raspy, emotional
- **Pop** (Taylor Swift) — female mezzo, conversational, clear
- **Opera** (Pavarotti) — male tenor, full voice, vibrato
- **Mugham** (Alim Qasimov) — male, ornamented, traditional
- **Hip-hop** (Kendrick Lamar) — rap, rhythmic, varied flow

## For AI music (Suno)

Specify vocals clearly:
```
[Vocals: female alto, lead throughout, doubled with male tenor on chorus]
```

Or per section:
```
[Verse: male baritone, intimate]
[Pre-Chorus: male falsetto, building]
[Chorus: female alto lead + male harmonies, powerful]
[Bridge: duet, trade lines]
```
