closing the window must have changed the cavity's resonance frequency
(think a flute). In any instrument it's the standing wave (a string or
the pressure inside a cavity) that ensues from a mechanical
perturbation that in turn irradiates traveling pressure waves (sound)
at the same frequencies. The harmonics and other non-linear
interactions with the instrument which produce freq components other
than the latter give the instrument's tone (and a big headache to synth
designers)
