Orahan, god of creation in the mythology of the island of La Gomera, employs the Arrorró of Cantos Canarios by Teobaldo Power as a base upon which the Metaludio is built. The Arrorró becomes, therefore, musical raw material, which is transformed through a process of fractalization. This process, which uses several superimposed copies of the Arrorró, gives rise to what will be, after making artistic and pianistic decisions, the final work.  Orahan is dedicated to the Real Academia Canaria de Bellas Artes San Miguel Arcángel.
