No it isn't. If you put any piece of music that is harmonious through a device that analyses the frequencies you'll find three main notes and those give you the key. In C-major for example the main notes are C, E and G. The section will be in C even if the first note is E for example.

You can do this with software. There's a nice video of this here https://youtu.be/xVmkIznjUPE?t=24s
or you can upload a recording to get the chords https://chordify.net/
You can indeed fourier transform the music. I imagine the above software does so.
