But then from A-880Hz to A-1760Hz is also 12 semitones. In one case you have a change of 440Hz spread over 12 semitones. In the other you have a change of 880Hz spread over 12 semitones. So as you go up the pitch scale, each semitone consists of a slightly larger change in frequency than the semitone below it. That is why the pitch system is non-linear. There is no set number of (change in) Hz per semitone.
