To get this technique after recovering Cloud from the Life Stream go to Nibelheim with the Highwing, go to tifa's house and play the tune Do,Re,Mi,Ti,La,Do,Re,Mi,So,Fa,Do,Re,Do. A note should pop out of the piano from Zanghan, Tifa's martial arts instructor. After reading it you'll recieve the final heaven
