The Frozen Heart (Ice Worker's Song) is the opening song in Frozen. It is sung by the ice harvesters as they cut ice from a lake and load the blocks onto their sleds to take into town.

Lyrics

Ice Harvesters:
Born of cold and winter air
And mountain rain combining
This icy force both foul and fair
Has a frozen heart worth mining

So cut through the heart, cold and clear
Strike for love and strike for fear
See the beauty, sharp and sheer
Split the ice apart!
And break the frozen heart

Hyup! Ho! Watch your step! Let it go!
Hyup! Ho! Watch your step! Let it go!

Beautiful!
Powerful!
Dangerous!
Cold!

Ice has a magic, can't be controlled
Stronger than one! Stronger than ten!
Stronger than a hundred men!

Hyup!

Born of cold and winter air
And mountain rain combining!
This icy force both foul and fair
Has a frozen heart worth mining!

Cut through the heart, cold and clear!
Strike for love and strike for fear!
There's beauty and there's danger here
Split the ice apart!
Beware the frozen heart...
