Efter soundchecken repar vi gitarrsolot.

Because Swedish is a V2 language in main clauses: the finite verb normally comes in the second position.

Here, Efter soundchecken is placed first, so the verb repar must come next:

Efter soundchecken repar vi gitarrsolot.

If the sentence started with the subject instead, you would get:

Vi repar gitarrsolot efter soundchecken.

So repar vi is not a question here; it is just normal Swedish word order after a fronted time phrase.

The ending -en is the definite singular ending for many common-gender nouns in Swedish.

So:

• en soundcheck = a soundcheck
• soundchecken = the soundcheck

In this sentence, it refers to a specific soundcheck, so the definite form is natural: after the soundcheck.

Also, soundcheck is a borrowed word from English, but it behaves like a normal Swedish noun once it is in the sentence.

No. repar here comes from the verb repa, which means to rehearse in music, theatre, and similar contexts.

So:

• att repa = to rehearse
• vi repar = we rehearse / we’re rehearsing

For an English speaker, it can look confusing because repar resembles repair, but it has nothing to do with fixing something in this sentence.

Both can relate to practice, but they are not used in exactly the same way.

• repa is very common for rehearsing together, especially for bands, musicians, theatre groups, etc.
• öva is more general and often means practice a skill, piece, or instrument.

So in a band context, vi repar sounds very natural.
You could say vi övar på gitarrsolot, but that sounds a bit more like practicing the solo rather than rehearsing as part of a band session.

Because gitarrsolo is a neuter noun in Swedish: ett gitarrsolo.

The definite singular form of many neuter nouns ends in -t:

• ett solo → solot
• ett gitarrsolo → gitarrsolot

A useful thing to know is that Swedish compounds usually take their gender from the last part of the compound. Since solo is neuter, gitarrsolo is also neuter.

In Swedish, the definite article is often attached to the end of the noun instead of being a separate word.

So English:

the guitar solo

becomes Swedish:

gitarrsolot

This is very normal in Swedish. You do not add a separate the-word here.

Very often, yes. Efter means after and is commonly used as a preposition before a noun phrase:

• efter mötet = after the meeting
• efter konserten = after the concert
• efter soundchecken = after the soundcheck

It can also be used in other structures, but in this sentence it is simply a preposition introducing a time expression.

Yes. Swedish present tense often covers both meanings that English separates:

• we rehearse
• we are rehearsing

So vi repar can mean either one, depending on context.

In this sentence, the time phrase Efter soundchecken makes it sound like a planned or expected action after the soundcheck, but the Swedish form itself does not force one English tense choice.

It sounds fairly natural and somewhat informal, especially because of repar, which is common in musician talk.

The sentence is completely standard Swedish, but it feels like everyday speech rather than very formal writing. The borrowed noun soundcheck also gives it a modern, music-related tone.
