Wind-instrument harmonic phases are set by resonant pulse enhancement, not chance.

Evidence

Not every constructive addition of amplitude corresponds to a resonance. For example, the focal point of a lens has high wave amplitude, but there is no confinement to the focal point—waves are just passing through—and no echo back to a source. Confinement or return is essential to resonance. — Eric J. Heller, Why You Hear What You Hear- An…, 896 (#corroborates, via linked claim)
