Symphonic Thermal Pitch Drift Matrix
オーケストラ開演前チューニング＆楽器温度ドリフト対照表
Acoustic physics explaining why the oboe tunes the orchestra: speed-of-sound shifts under stage heat.
| Orchestral Family | Instruments | 15-Min Thermal Effect | Pitch Drift (Cents) | Concert Tuning Protocol |
|---|---|---|---|---|
| Oboe (Anchor) | 双簧管主副首席 | Dense blackwood stabilizes at 37°C thermal equilibrium fastest | ±1.0 cents (全团最稳定) | Pre-warmed upper joint; zero-vibrato straight concert tone |
| String Family | 第一/第二小提琴、中提琴、大提琴 | Stage lights heat strings, causing metal elongation | -3.0 至 -5.0 cents (自然偏低) | Strings must tune slightly crisp to offset thermal sagging |
| Brass Family | 小号、圆号、长号、大号 | Brass body heats up, increasing internal speed of sound | +5.0 至 +8.0 cents (自然偏高) | Brass tune sharp as they warm up; pull main slide 3mm |
| Upper Woodwinds | 长笛、短笛 | Metal tube warms rapidly with air turbulence | +4.0 至 +6.0 cents (自然偏高) | Flute pulls headjoint 2mm to match oboe core |
