1. Educational & Repertoire Fair Use
All slide position charts, harmonic partial derivations, and public-domain solo concerto guides hosted on TbmLib are provided for music education, personal rehearsal, and classroom reference.
2. Acoustic Physics & Intonation Disclaimer
Trombone slide positions, physical centimeter extensions, and temperature tuning shifts are modeled on standard atmospheric conditions (20°C / 68°F, ISO 16 A4=440Hz/442Hz). Actual pitch may vary depending on bore size, bell alloy, mouthpiece cup depth, and embouchure.
