Korsangen krever god pustestøtte.

Korsangen is a compound noun:

• kor = choir
• sang = singing / song
• korsang = choral singing / choir singing
• korsangen = the choral singing / choral singing in general

In this sentence, korsangen is best understood as choral singing as an activity or style of singing.

The ending -en is the definite article for many masculine nouns in Norwegian.

So:

• en korsang = a choral song / choral singing
• korsangen = the choral singing

Norwegian often uses the definite form where English might use a more general expression. So even though English says Choral singing requires good breath support, Norwegian can naturally say Korsangen krever god pustestøtte.

Krever is the present tense of the verb å kreve, which means to require or to demand.

Examples:

• å kreve = to require
• krever = requires / require

So:

• Korsangen krever ... = Choral singing requires ...

Unlike English, Norwegian verbs do not change depending on the subject:

• jeg krever
• du krever
• den krever

The form stays krever.

God agrees with the noun pustestøtte.

Here, pustestøtte is a singular noun, and it is treated grammatically so that the correct adjective form is god.

Compare:

• en god sang = a good song
• ei god bok = a good book
• et godt råd = a good piece of advice
• gode bøker = good books

So in this sentence:

• god pustestøtte = good breath support

Yes, pustestøtte is a compound noun.

It is built from:

• puste / pust = breathe / breath
• støtte = support

Together, pustestøtte means breath support, especially in singing or voice training.

Compound nouns are very common in Norwegian, just as in English:

• kor + sang → korsang
• pust + støtte → pustestøtte

In Norwegian, nouns often appear without an article in some general statements, especially when talking about something abstract or uncountable.

Here, pustestøtte is being used as a general concept:

• god pustestøtte = good breath support

That is similar to English, where we also usually do not say a good breath support.

So the phrase is natural as:

• krever god pustestøtte = requires good breath support

No, this is standard Norwegian sentence order:

• Korsangen = subject
• krever = verb
• god pustestøtte = object

So it follows the basic pattern:

Subject + Verb + Object

That makes this a very straightforward main clause.

In some contexts, you may see a bare noun in Norwegian, but korsangen sounds more natural here when speaking generally about the discipline or type of singing.

So:

• Korsangen krever god pustestøtte = very natural
• Korsang krever god pustestøtte = less natural in this context

Norwegian often uses the definite form for general categories in a way that can feel unusual to English speakers.

Yes. A few natural alternatives are:

• Å synge i kor krever god pustestøtte.
  = Singing in a choir requires good breath support.

• Korsang krever god pustestøtte.
  Possible, but usually less idiomatic than korsangen here.

• Det krever god pustestøtte å synge i kor.
  = It requires good breath support to sing in a choir.

All of these are understandable, but Korsangen krever god pustestøtte is a compact and natural sentence.

A rough pronunciation guide for an English speaker could be:

• korsangen ≈ KOOR-sang-en
• krever ≈ KREH-ver
• god ≈ good / gooh
• pustestøtte ≈ POOS-teh-stut-teh

A few useful notes:

• Norwegian r varies by dialect.
• o in kor is longer than English speakers often expect.
• The tt in støtte is pronounced clearly.
• The vowel ø does not exist in English, so it may take practice.

Exact pronunciation depends on dialect, but this will get you close enough to recognize and say it.
