  • A flue pipe's sound arises from air passing a slit and striking a wedge
  • A mouthpiece's popping frequency reveals how it extends effective pipe length.
  • Air absorption can be modeled as equivalent surface absorption scaled by room volume
  • Air reed pitch is set entirely by resonator length and pipe openness.
  • Flue pipes sound through a self-oscillating vortex called the air reed.
  • Increasing flue airflow makes pitch jump upward in discrete overblown steps
  • Raising airflow or lowering the cut-up makes flue pitch jump discontinuously
  • Random air density fluctuations, not single molecules, make the sky blue.
  • Upward note bending fails because airflow cannot reinforce both resonances at once
