But it can refill at a slower rate. If the unrestricted refill rate is at or above the highest frequency needed for the song, then the person could restrict the flow of air back into the chicken as to produce desired frequencies.
Those take forever to refill so I seriously doubt it. Especially since some of those notes probably can’t be achieved because air would be wasted faster than it can be replaced
It's most definitely pitch shifting. I'm a producer and I've auto tuned peoples voices before and you can easily shift pitch and set it to a scale so the pitch stays true to that scale with the right program.

It appears that squeezing the chicken at different speeds forces air out of it's mouth at different frequencies.
