From Zelda Wiki.org
The
Elegy Of Emptiness is taught by the
King of Ikana in
Majora's Mask after
Link defeats him. This song leaves a exact replica of the form Link is in at the time. It was composed by
Flat. This song is required to scale up the
Stone Tower as well as in the
Stone Tower Temple. A total of four replicas can exist at any given time, one of each of Link's forms. The
Deku form is least commonly used, however, as it is too light to be of any use.
