I hope everyone here realizes this is a simplification -- not every 
sound is periodic,  and even many pitched tones are not periodic (bells 
are a good example). And even if you consider only the lowest sinusoidal 
component, it may not have the same frequency as the fundamental of 
another sound with the same perceived pitch. I could go on, but you get 
the idea. Pitch is perceptual, frequency is physical, and the 
correspondence is not always simple.
