First off, the opening with the ice farmers is never paid off. Why open with a song about their hardwork and spend a few minutes with them just for us to never see them again? Is there an ice farmer village and way of life? Do the live in huts or igloos or regular old houses in the various towns? No one knows because this was pointless. There had to be a more economical way to introduce Kristoff as a boy then that. It sets us for a different sort of thing (the vibe from that opening is pretty different than from the rest of the film) and isn't paid off. Thanks for wasting my time already movie!
The opening serves several purposes, in fact. It is in the spirit of openings such as The Little Mermaid (the sailors sing about the mysterious sea... none of them really show up again), Pocahontas (The Beating Drum establishes their way of life, and we barely see them again), Aladdin (that merchant sings about the setting and never shows up again), Hunchback of Notre Dame (the jester delights some kids and segues into the movie proper, with the kids never showing up again), etc., with the point of the opening being to establish the tone of the movie and the setting of the movie. Like the sailors singing about the mysteries of the ocean, the (other) sailors in Pocahontas singing about the mysteries of the new world, Belle singing about what's beyond her village, we have the ice cutters singing about the perils, mysteries, and benefits of living in a world filled with cold and ice...
It serves THREE key purposes:
1) Apart from establishing the tone of the movie, it's a great place to show Kristoff's origins... and that scene shows what Kristoff will grow up doing. It shows, through the adults, the hard work and sacrifice he'll grow into living out. We don't see it in the movie, but the opening makes it clear that this is what Kristoff is doing for a living once we meet him as an adult and we now know how he does it and how much of a struggle it is, establishing his work ethic, his resilience, and how he finds fun even in grueling labor. We don't see the other ice workers again because the movie "fast-forwards" about 15 years, meaning they might all just be retired or even dead. It seems like Kristoff is one of the sole ice merchants in the kingdom at that point.
2) It establishes the setting of the movie. Like the merchant's song in Aladdin, it establishes the beauty and perils of this Nordic world. It very quickly establishes that, unlike Lion King, Little Mermaid, Aladdin, or other Disney movies, this is a kingdom of ice and rock, built on the fjords, beautiful yet tough. It's the most easy and accessible way to very, very quickly bring people into the movie and immerse them, as a teaser of things to come once the eternal winter hits... which ties into...
3) The lyrics. The song the ice cutters sing is FILLED with meaning, and they practically set up the whole premise of the movie, which describes both the kingdom, the properties of ice, and the entire character arc for Anna and Elsa:
"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."
That's basically a giant foreshadowing of Elsa and Anna's entire story arc, with strong references to Elsa's nature (even the "let it go" part was entirely intentional). It's a brilliant way to tie in the themes of the movie, establish the setting of the movie, and introduce one of the lead characters (and his reindeer) in a concise and effective manner.
