What a definition of a Fourier transform...
For simplicity, let's say it's a way to look at signal in a different way. We normally look at it as a function of time: a song plays as time pass by. But you could look at it in the "frequency domain", meaning you look how much of each frequency is present in all of the signal/music. A Fourier transform let you go from one perspective to the other.
