Wind God's Aria
Description
Note: Learning the Wind God's Aria before beating the Forsaken Fortress 2 will crash the game due to wrong animation sets. See here for more info.
It is posible to enter Gale Isle and learn the Wind God's Aria without the Iron Boots or without the Skull Hammer. This can be useful for routing purposes.
Contrarely to obtaining the Earth God's Lyric early, there are no complications to learning the Wind God's Aria early (no possibilities of softlocking when entering the island with Makar later on)
Without Iron Boots
You can skip the iron boots requirement by pulling out the Wind Waker, walking a little towards the statue you want to break with the hammer, then pulling out the Wind Waker again, and so on. This works because you are not vulnerable to strong winds right after pulling the Wind Waker. This allows you to get really close to the statue without Iron Boots. Use the Hammer jumpslash to break it.

Chest Storage with Iron Boots
Chest Storage from KoRL
With Chest Storage, from the boat, you can leaf and land on one of the pillars on the eastern side of Gale Island. You can then climb up it and leaf to a higher ledge on the island. With Chest Storage, you can simply clip through the island somewhere on the back and enter the loading zone without the hammer. You can then proceed by learning the Wind God's Aria.
Bomb Push Clip and Tingle Balloon

Zombie Hover

Zombie Hover to the higher ledge of the island and use the tingle tuner to heal yourself. You can clip OoB by simply hanging from a ledge close to the wall and letting go, no need for a roll clip or a ledge clip.
To do this without the Tingle Tuner, zombie hover to the pillar on the western side of the island that has hearts on it and then leaf to the island once healed.
Miscellaneous
Morth entry
While pretty much useless apart from being funny, it is interesting to note that you could potentially use morths to enter Gale Island early. You can get morths by digging them out from an Outset Island digging spot (behind Grandma's house). By getting them to attach onto Link and entering KoRL without going into the water, you can bring them all the way to Gale Island. To get onto Gale Island from your boat without going into the water, you need the hookshot. Using the extra weight from having morths attached to Link, you can get near the stone without iron boots. If you throw a frozen morth onto the stone, it will break because frozen enemies have skull hammer damage type. While this is funny, it is really slow and also requires some late game items to fully perform, namely power bracelets, hookshot and ice arrows.
