Chiff-voiced open pipes briefly sound an octave high at onset

Evidence

If a pipe is overblown, its f0 jumps to the next higher mode that the resonator can support: up one octave to the second harmonic for an open pipe, and up an octave and a fifth to the third harmonic for the stopped pipe. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1211 (#expands, via linked claim)

Careful listening to pipes voiced with a chiff will reveal that open pipes start briefly an octave high since their first over­ blown mode is the second harmonic, and stopped pipes start an octave and a fifth high since their first overblown mode is the third harmonic. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1471 (#expands, via linked claim)
