Source: a lip-buzzed low brass note (tuba-like). A band-limited saw carries the buzz, a soft square adds the hollow odd-harmonic core, a sine one octave down gives the weight, and a little band-passed breath noise sits on the attack.
Body: the bell and tubing act as a low-pass whose cutoff starts open and closes while the note sounds (bright "blat" first, dull "oom" after), plus a gentle bump near 2.5x the pitch.
Envelope: ~25 ms soft attack, a short swell, then an exponential fall. The pitch scoops up from a little flat into the target, the classic sloppy brass entrance.
Gesture: two notes, the second a few semitones lower, a touch longer and duller, played after a small gap. The descent is what makes it comic: resigned and slightly late. A shallow vibrato appears only on the tail of each note.
Variation: `rng` shifts the tuning of each note by a few cents and varies the breath noise.
