Tune of Echoes
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 (opens) the many Time Portals scattered across the land of Labrynna. Step into an open Time Portal to travel to the opposite age.
The symbol for this tune, which is the courage symbol also appears on Farore's Pearl, as Farore is the godess of courage, in The Wind Waker and it also appears on the Ancient Sky Book
