# Pitch Range — VoiceNet dimension guide

*Category:* Rhythm & Timing · *code:* `vn_RANG` · *slot:* 44

This dimension measures the vertical movement of pitch across the segment. Merge the `__high` / `__low` LoRA from `laion/moss-voicenet-dimension-loras` at 25/50/75/100/125%. Costs are shifts vs. the 24-sample neutral baseline.

**TL;DR.** **Pitch Range** controls the vertical movement of pitch across the segment. The **__high** LoRA shifts it +0.76 at 125% (worst cost: burst-blend -0.36); the **__low** LoRA shifts it -0.04 at 125% (worst cost: burst-blend -0.30). The **__high** direction is the stronger, more reliable knob here.

## ▲ HIGH — Pitch Range __high

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.103 | — | — | — | — |
| 25% | 0.226 | +0.12 | -0.03 | -0.09 | +0.02 |
| 50% | 0.287 | +0.18 | -0.04 | -0.14 | +0.07 |
| 75% | 0.665 | +0.56 | -0.04 | -0.34 | -0.14 |
| 100% | 0.841 | +0.74 | -0.09 | -0.39 | -0.18 |
| 125% ★ | 0.860 | +0.76 | -0.08 | -0.36 | -0.23 |

- **EmoNet emotion** — ↑ Triumph (+0.64), Anger (+0.64), Elation (+0.62); ↓ Contemplation (-0.72), Relief (-0.61), Contentment (-0.52)
- **VoiceNet dimension** — ↑ Arousal (+0.96), Dynamic Arc (+0.95), Metallic Character (+0.94); ↓ Warmth (-0.90), Whisper-Talk Style (-0.82), Vulnerability (-0.82)

Merging **Pitch Range __high** ramps the dimension: at the recommended **125%** dose the measured Pitch Range score moves from a 0.10 baseline to 0.86 (a +0.76 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is a steep cost — the biggest hit is to **burst-blend** (-0.36); across the board genuineness -0.08, burst-blend -0.36, speech quality -0.23. Emotionally it reads as Triumph (r 0.64), Anger (0.64) and Elation (0.62), and it moves away from Contemplation, Relief and Contentment. On other voice dimensions it co-moves most with Arousal (0.96), Dynamic Arc (0.95) and Metallic Character (0.94), while pulling down Warmth, Whisper-Talk Style and Vulnerability. Practical call: merge __high at **100–125%**; expect Triumph and Arousal to rise and burst-blend to fall. If you don’t want Triumph bleeding in, offset it with a prompt cue toward Contemplation to keep the pitch range shift without the side-effect.

## ▼ LOW — Pitch Range __low

| dose | target | Δtarget | Δgenu | Δblend | Δqual |
|---|---|---|---|---|---|
| baseline (0%) | 0.103 | — | — | — | — |
| 25% | 0.148 | +0.05 | -0.04 | -0.11 | -0.08 |
| 50% | 0.115 | +0.01 | -0.04 | -0.27 | -0.19 |
| 75% | 0.109 | +0.01 | -0.01 | -0.31 | -0.23 |
| 100% | 0.156 | +0.05 | -0.02 | -0.28 | -0.22 |
| 125% ★ | 0.067 | -0.04 | +0.02 | -0.30 | -0.30 |

- **EmoNet emotion** — ↑ Elation (+0.39), Interest (+0.36), Malevolence/Malice (+0.35); ↓ Fatigue/Exhaustion (-0.42), Sadness (-0.32), Disappointment (-0.27)
- **VoiceNet dimension** — ↑ Metallic Character (+0.80), Arousal (+0.78), Tension (+0.74); ↓ Vulnerability (-0.40), Oral Resonance (-0.32), Disfluency (-0.31)

Merging **Pitch Range __low** dials back the dimension: at the recommended **125%** dose the measured Pitch Range score moves from a 0.10 baseline to 0.07 (a -0.04 shift). The dose-response is clean and monotonic — each step pushes the dimension further. That reach is a steep cost — the biggest hit is to **burst-blend** (-0.30); across the board genuineness +0.02, burst-blend -0.30, speech quality -0.30. Emotionally it reads as Elation (r 0.39), Interest (0.36) and Malevolence/Malice (0.35), and it moves away from Fatigue/Exhaustion, Sadness and Disappointment. On other voice dimensions it co-moves most with Metallic Character (0.80), Arousal (0.78) and Tension (0.74), while pulling down Vulnerability, Oral Resonance and Disfluency. Practical call: merge __low at **100–125%**; expect Elation and Metallic Character to rise and burst-blend to fall. If you don’t want Elation bleeding in, offset it with a prompt cue toward Fatigue/Exhaustion to keep the pitch range shift without the side-effect.
