But any periodic wave's shape can be *completely* described as the sum
of sines of various frequencies and phases. Therefore timbre *is* a
function of frequency.

... by extending the frequency response.
If you can hear the difference between a 22 kHz sine wave and a 22 kHz
square wave, then you are hearing frequencies at 44 kHz or above.
Either that, or you are hearing distortions in the playback system
induced by ultrasonic content, which is quite possible.
