Tune of Echoes

In The Legend of Zelda: Oracle of Ages, the Tune of Echoes is the first tune that Link learns to play on the Harp of Ages. Nayru's apparition teaches it to him when he takes the harp.

The Tune of Echoes awakens the many Time Portals scattered across the land of Labrynna. He must step into an open Time Portal to travel to the opposite age.
