Returning to Nibelheim
The town of Nibelheim, which is Tifa and Cloud’s hometown, is host to several different side quests that are available at various points in time throughout the game.
Your first visit to Nibelheim is during the flashback cutscene when the team arrives in Kalm. Ensure that you enter Tifa’s house and attempt to play on her piano (choose to have Cloud try to “jam on it”).
The second time you encounter Nibelheim is when your team travels there on Disc 1. Aside from a host of items that are available in and throughout the town, this is also the first time that you can complete the side quest to obtain Vincent, one of the optional/secret characters. Check out the Secret / Optional Characters section under Vincent for more information.
Disc 2 Visit
You can revisit Nibelheim as soon as you obtain the Highwind after escaping from Junon. Revisit the town, and if you had chosen to jam on Tifa’s Piano during the flashback sequence in Kalm, you would now be able to obtain an Elemental Materia by playing Tifa’s piano again.

You can only complete this next portion once Cloud has returned to your party, but you can also complete it in Disc 2. If Cloud has not yet joined your party, you must wait before doing this portion of the side quest.

Add Tifa to your party, travel to her house, and choose to play Tifa’s Piano in her room. Play the following tune, which is the main theme song from the World Map:
