Harp of Ages

In, the Harp of Ages is a mythical instrument that belonged to Nayru, the Oracle of Ages. Link finds the Harp in a secret room of Nayru's house where an imprint of Nayru teaches him the "Tune of Echoes". This apparition hoped that a hero had found the harp and would use it to save the land.

The Harp of Ages allows Link to control the currents of time to Warp between the past and present ages of Labrynna by playing certain tunes on it. The three tunes Link learns to play on the Harp are the Tune of Echoes, the Tune of Currents, and the Tune of Ages.

If Link attempts to travel through time in certain areas, he will be sent back "by a strange force". These areas are Yoll Graveyard, the Sea of No Return and the Black Tower grounds. He also cannot travel through time inside dungeons. This exists to prevent sequence breaking.
