What's the name of the bit of music played after you win a fight when playing Final Fantasy X?

Like... for example when you beat someone it plays this music... it does it on Final Fantasy VII too. If you've ever seen the movie "Final Fantasy VII: Advent Children" and after Tifa knocks the guy under the rubble and his phone rings, it's his ringtone. Anybody know what it's called? I just got the sudden urge to look up how to play it on guitar.
