The Ocarina glitch allows you to walk through certain objects and walk above rooms, allowing for many large tricks and sequence breaks.
There are currently 5 different methods to activate the Ocarina Glitch, the main method being off staircases.
For this method, you need the Ocarina of Wind and a staircase that leads to another room/screen (mainly staircases in dungeons as well as pond stairs).
To activate the glitch, get in front of the staircase, then press up and play the Ocarina 1 frame afterwards. If done correctly, Link will stop playing the Ocarina immediately and everything in the room freezes.
While Link is still somewhat inside the staircase, you can just easily walk out of it. If you hold up for too long, Link will pop out of the staircase and walk down the stairs, cancelling the Ocarina Glitch, so make you sure only tap the button.
While in the frozen room state:
Going into another room by scrolling the map (not loading a completely new area like going up a staircase or leaving a dungeon) will unfreeze everything. The above effects will deactivate but you still have the Ocarina Glitch active. Playing the Ocarina will completely cancel the freeze and all effects of the Ocarina Glitch.
While the glitch is active, your height in a room will be preserved. This means you cannot fall into pits, and you can go up stairs to access a higher layer of a room, but cannot go down again. Once you are on a higher layer of the room, you will be able to walk over everything on the lower layer, including walls. However, if you transition the screen while over a lower layer, your height will be set back to the lower layer and you will not be able to walk over walls as you could before, so be careful to transition the screen to where you start on the same height level as the previous screen.
There aren't many ways to access a lower layer again, so once you go up a layer, you will have to stay there in most rooms. The current known methods to access a lower layer again are:

While in the frozen room state, using items that make a sprite appear like the Cane of Pacci or the Bow will make the sprite appear and stay in place. You can repeatedly use items to create more sprites or mess with existing sprites and have them stay in place, then use the Ccarina to unfreeze and have everything go off at once. Creating too many sprites will cause sprites to start disappearing or flickering, though the collision remains. Unfortunately, it has no known uses, but it's fun to play around with.
Uses for the Ocarina Glitch:
Any%:
100%:
If you open a door without entering the house, you can activate the Ocarina Glitch using the open doorway.
Methods for opening the door include dying and reviving with a fairy the frame you open the door, and using an NPC to push you out of the doorway after you open the door.
This is currently used to enter Temple of Droplets without the Flippers and to get the Power Bracelets early.

You can activate the Ocarina Glitch off of certain cutscenes by playing the Ocarina on the same frame the cutscene starts. Cutscenes where a door opens seem to work best for this. Uses: Moblin Fight Skip in Palace of Winds, Power Bracelets Skip

By standing above a key block, playing the Ocarina and then using a small key on the key block by pressing R, the animation will get interrupted and the Ocarina Glitch activates. Since there aren't many key blocks in the game, there is only 1 known place where this is possible.

Playing the Ocarina and closing/opening a textbox during the animation will cancel it and activate the Ocarina Glitch. There is currently only 1 known place where this is possible.
