Tune of Echoes
How to Acquire
After journeying through the Fairies' Woods, Link will reach the Wing Dungeon. However, the building will collapse as soon as he gets close. Link will then hear from the Maku Tree that he must go to Nayru's House. When he arrives there, he can move the statues that near Impa to find a secret staircase. In the basement of Nayru's House, Link will find the Harp of Ages. Link will immediately hear from Nayru and learn the Tune of Echoes.
The Tune of Echoes has the ability to create Warp Portals. However, unlike the Tune of Currents and the Tune of Ages, Link cannot just use this Tune at any location in the game. There are specific time portals scattered throughout the land of Labrynna and his Tune will only be useful when used around these specific locations.
