Can someone tell me why I hear a Legend of Zelda theme in mp3 related?

That flute(?) melody, I was sure it was some ocarina song from OoT, but I checked the game's soundtrack and could not place it.

This happens to me a lot. Often I seem to recognize melodies or themes, yet my mind is unable to fully connect the dots. I'm musically illiterate, so it occurred to me that one thing that could be happening is that the new piece that I hear is not exactly the same as the one in my memory, some parameters are changed, or shifted, maybe tone, or tempo, or rhythm (fuck, I don't even know the proper names), and maybe that's enough to make my mind unable to match them up.
