Middle C is 261.63 Hz. The next half-step up (C#) is 277.183 Hz.

Why are these notes, while a tone at, say, 265 Hz, is not? Or what about 269.1488 Hz -- nearly absolute middle of the two?

Why do we recognize certain frequencies as notes?

The absolute frequency doesn't matter. You can adjust tuning any amount and it won't matter; what matters are the ratios between notes, as that allows form pleasing chords when notes combine. This is a really good video about .
