Majoras Mask Help!

Well, My Zelda Collectors Disc arrived today, And I have got quite far, I have 6 masks (Deku Mask, Faerie Mask, Kafei Mask, Bremen Mask, Bomb Mask). But im really confused, I only know Song of Time and Song of healing, But theres like 3 or 4 other songs I have (Double time, Inverted Time and some others) which dont show up?

So can someone do me favour and list the instructions for the song and what they do?

If I'm correct it's like this :

Song of Double Time : play each note of the Song of Time twice.
Advance 12 hours forewards.

Song of Inverted Time : play the Song of Time backwards.
Time goes twice as slow.

These song don't show up the list.

Ah, Thank you , Now I should be able to do the game a little bit more easily.
