Either the Sun's Song or Song of Storms. You don't get anything worthy, just a pink fairy or rupees. And holy shit, dude. Make individual sentences, not 9 sentences crammed into one sentence.
What insane forgot to mention is that there are some huge Fairy that replinsh all magic power+hearts, only show up with either sung son or song of storms.
There's only one or two places that do that, and one that I know of is at the pole just outside the entrance to Goron Village. The place he mentions isn't one of those places though, and that's why I didn't bother to mention it.
the tomb of the royal family where you get the sun song, the first chamber where you need to lit some torches and kill some keese's. i would really recomend for you to try and grab a lot of magic beans and start planting them on every soft soil spot, once you get to be an adult the magic beans will have grown onto leaves, you can use them to get to several heart pieces, and other stuff including some gold skulltullas and making travel from some points easier in some areas.
