Song of Time

In Ocarina of Time, the Song of Time can be used in the Temple of Time to unlock the passage to the Master Sword once you have the three Spiritual Stones. It can also be used to get rid of and bring back certain blocks.

In Majora's Mask, the Song of Time warps you back to the dawn of the first day. Any items or unused rupees you have when playing the song will be lost. However masks, upgraded weapons (except razor sword), dungeon maps, and compasses will be kept.

In Twilight Princess, it serves as background music for the entrance to the Temple of Time, and a remixed version is used in the battle against Ganon's Puppet Zelda.

Majora's Mask Tricks
In Majora's Mask, a couple of tricks involving this song can alter the regular flow of time. Scarecrows will hint at these variations if Link chooses to speak with them. While they make progressing through the game easier, they are far from necessary to complete it.

When Link plays each note twice in the Song of Time, time will warp to the next instance of 6:00 am or 6:00 pm. This is known as the "Song of Double Time."

When Link plays the Song of Time backwards, all events directly related to the flow of time will move at half-speed. This affects the flow of time, and scripted movements such as Anju's movements, but not events that aren't directly involved with the flow of time such as an enemy's attack pattern or the rate at which Link can move. This variation of the tune is called the "Inverted Song of Time".
