Rom Zelda Ocarina Of Time ((link)) -

Furthermore, the game integrated music not merely as background ambiance, but as a core gameplay mechanic. The Ocarina of Time itself allowed players to play melodies using the controller’s buttons, affecting the game world directly. Whether it was changing day to night, summoning a horse, or warping across the map, music was the key to solving puzzles and traversing the world. This mechanic bridged the gap between the player and the avatar; when Link learned a song, the player learned it too. The soaring melody of the "Song of Time" or the haunting strains of the "Song of Storms" became ingrained in the cultural memory of gamers, elevating the soundtrack from a passive experience to an active, participatory one.
