Head towards Kakariko Village. Enter during the day. First thing you should do is introduce yourself to the clock soldier. His times come in handy.
Next meet the Boss of the Carpenters...everything is worthless to him. Notice the well in the middle of the village. Leave it alone for now, but know it will drive you batty at a later point in the game.
Go to the southern area of the village. Here you will meet a girl who has lost her seven Cuckoos. You must collect them.
1) One is next to her.
2) One is by the village entrance.
3) One is by the tree near the entrance.
4) There's one behind the gate beyond the windwill door. To get to this one, run up the path leading to the windmill door with a
chicken in hand. Jump off, and you'll float thanks to the chicken you
are carrying. Toss the chicken right before hitting the gate so you can grab on. Once you climb the gate and toss the chicken over the fence by the backdoor entrance so you can grab him later and take him to the coop. (There's a hole you might want to fall through to collect some underground goodies).
5)
While on this side of the fence, head up the ladder along the ledge and get the chicken up above. Toss him to a place where you can grab him later.
6) You'll have to use your "floating chicken" move to get the chicken on the ledge by the Skulltulla house. Jump from the area with all of the construction.
7) Smash open the crate next to the first house you pass in the village to the left by rolling into it. This is the final Cuckoo.
Once you give the girl all of her Cuckoos back, she'll reward you with an EMPTY BOTTLE. YAY!
Now head down the path next to the chicken coop (SE corner), which leads to the Graveyard.
Explore the Graveyard. If you're there during the day, you'll run into a kid imitating Dampe, the Gravedigger. Noted.
Go to the very back of the Graveyard, where you will find two graves, a stone, and an image of the Triforce in the ground. Stand on this patch of land and play Zelda's Lullaby on your Ocarina. This will reveal a hole which you will fall down.
Now you are in the Royal Family's Tomb. Move forward and kill all of the bats. Doing so will raise the bars on the door. Pass through it.
In this room you will encounter many ReDeads. Simply avoid them at this time, as they will suck the life right out of you. Pass through the door on the opposide side of the room and approach alter. Check it out.
Written on the alter is the Sun's Song. This will speed up time from dusk to dawn and dawn to dusk.
Go back into the room with the ReDeads and play your new Sun's Song for them. This will freeze them in place so you can kill them.
Exit the tomb. All we really go from there, so far, is the Sun's Song. Trust me, you'll be happy to have it. Speeding up time is necessary.
Now, head back into Kakariko Village, and up the path toward Death Mountain.
