B♭3
Concert D♭3
Written B♭3 on the treble staff

The lowest note on the horn: all six fingers, the left-pinky B♭ paddle, and the right pinky still holding the low C key. It answers to warm, unhurried air and a loose jaw — squeezing the reed makes it honk or jump up an octave. A pad leaking anywhere down the bell will kill this note before any other, so it doubles as a quick health check on the instrument.
