Alternate fingerings for Throat Bb
- Resonance fingering (both hands shading): Register key + A key + Left middle (hole 2) + Left ring (hole 3) + Right middle (hole 5) + Right ring (hole 6) + Right pinky F/C key. Use on longer B♭s where there is time to set the extra fingers — it sounds fuller and sits closer to pitch.
- Side-key B♭ (G♯ key with the first side key): G♯ key + Side key 1. Use in trills and quick passages around A and B where a clear, ringing B♭ matters more than the security of the standard fingering.
