Increasing flue airflow makes pitch jump upward in discrete overblown steps

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)

Categorization

  • XREF: connects to: Upward note bending fails because airflow cannot reinforce both resonances at once; Raising airflow or lowering the cut-up makes flue pitch jump discontinuously; Overblowing a pipe jumps its pitch to the next resonator-supported harmonic — David Howard, Jamie Angus, coustics and Psychoacoustics, 1211 (+1 more)
