Spinnet følger tross alt musikkfrasen.

Here, spinnet is a noun, not a verb.

It is the definite singular form of spinn, so it means the spin.
That makes the sentence structure:

• Spinnet = the subject
• følger = the verb
• musikkfrasen = the object

A learner might confuse spinnet with a past participle or some other verb-related form, but in this sentence it functions clearly as a noun.

Because Norwegian usually puts the definite article onto the end of the noun.

So:

• et spinn = a spin
• spinnet = the spin

and

• en musikkfrase = a musical phrase
• musikkfrasen = the musical phrase

This is one of the biggest differences from English. Instead of saying the spin, Norwegian normally says spin-the, built as one word.

• spinn is neuter, so its definite singular form is spinnet
• musikkfrase is a common-gender noun in this sentence, so the definite singular is musikkfrasen

In Bokmål, some nouns can vary between masculine and feminine usage depending on style and preference. But musikkfrasen is a perfectly normal definite form.

Følger is the present tense of å følge = to follow.

Examples:

• jeg følger = I follow / I am following
• du følger = you follow
• han følger = he follows
• spinnet følger = the spin follows

Unlike English, Norwegian does not add a special ending just for he/she/it. The same present-tense form is used with all subjects.

Tross alt is a fixed expression meaning something like:

• after all
• all things considered
• when all is said and done

It is not usually best understood word-for-word. Even though tross relates to despite and alt means all/everything, the full expression works idiomatically.

So in this sentence, tross alt adds a nuance like:

• in the end
• despite earlier doubt
• after all

It often suggests a mild contrast with what one might have expected before.

Because Norwegian main clauses normally follow the verb-second pattern.

In this sentence:

• Spinnet = first element
• følger = finite verb in second position
• tross alt = adverbial
• musikkfrasen = object

So Spinnet følger tross alt musikkfrasen is a very normal word order.

A version like Spinnet tross alt følger musikkfrasen would sound wrong in ordinary Norwegian main-clause word order.

Here, følge takes a direct object, so musikkfrasen comes directly after it with no preposition.

That is similar to English:

• follow the phrase
• følge musikkfrasen

Depending on context, følge can mean:

• physically go after something
• track something
• stay in line with something
• correspond to the development of something

In this sentence, it most likely means that the spin follows the musical phrase in structure, timing, or movement.

Yes. You could say:

• Tross alt følger spinnet musikkfrasen.

That is also correct, but the emphasis changes slightly.

When tross alt comes first, it is more strongly highlighted. Because Norwegian is a verb-second language, the verb still has to come next:

• Tross alt = first element
• følger = second element
• spinnet = then the subject

So Norwegian does not say Tross alt spinnet følger musikkfrasen in a normal main clause.

Because the noun is definite here.

• musikkfrase = a musical phrase / musical phrase
• musikkfrasen = the musical phrase

If the sentence used the indefinite form, it would mean something different:

• Spinnet følger en musikkfrase = The spin follows a musical phrase

But the given sentence refers to a specific phrase, so musikkfrasen is the right form.

A rough pronunciation guide:

• spinnet ≈ SPIN-neh
• følger ≈ FUHL-ger or FURL-ger
  The ø sound does not exist naturally in English, so learners usually need practice with it.
• tross alt ≈ tross ahlt
• musikkfrasen ≈ moo-SIKK-frah-sen

A few helpful notes:

• rr is not present here, so nothing especially difficult there
• the ø in følger is the main sound English speakers usually need to work on
• stress is usually clear from the word shape: MUsikkfrase in citation form, but in connected speech the rhythm may soften a little depending on dialect

Yes, it is natural and grammatically straightforward.

It has a very standard structure:

• definite subject noun
• present-tense verb
• sentence adverbial
• definite object noun

The only thing that may feel slightly specialized is the vocabulary, depending on context. Spinnet and musikkfrasen sound like they belong to a discussion of music, dance, movement, or artistic form. But grammatically, the sentence is completely normal.
