Depois que escolhemos o repertório, entramos na cabine.

Depois que means after when it introduces a full clause with a conjugated verb.

• depois que escolhemos o repertório = after we chose the repertoire
• Here, que connects depois to the clause escolhemos o repertório

A useful comparison:

• depois que escolhemos o repertório = after we chose the repertoire
• depois de escolher o repertório = after choosing the repertoire

So depois que is used before a finite verb, while depois de is used before an infinitive or noun phrase.

Escolhemos is the preterite form of escolher for nós.

In this sentence, it shows a completed action in the past:

• first, we chose the repertoire
• then, we entered the booth

So the speaker is narrating a sequence of finished events.

Compare:

• escolhemos = we chose
• escolhíamos = we used to choose / we were choosing
• escolhermos = for us to choose / when we choose, in certain structures, often with the personal infinitive or future subjunctive contexts

Here, the simple past is the natural choice.

This is a very common source of confusion.

In Brazilian Portuguese, escolhemos can mean either:

• we choose or we are choosing in the present, depending on context
• we chose in the preterite

The form is identical. Context tells you which meaning is intended.

In this sentence, the past meaning is clear because the whole sentence describes a sequence of completed actions:

• Depois que escolhemos o repertório, entramos na cabine.

The same thing happens with entramos, which can also be present or preterite depending on context.

Portuguese often omits subject pronouns when the verb ending already makes the subject clear.

Here:

• escolhemos clearly means we chose
• entramos clearly means we entered

So nós is not necessary.

You could say:

• Depois que nós escolhemos o repertório, nós entramos na cabine.

But that sounds more explicit or emphatic. In normal speech and writing, leaving out nós is very common.

Portuguese uses definite articles more often than English does.

So where English might say simply we chose repertoire in some special context, Portuguese normally says:

• escolhemos o repertório

Here, o means the, and repertório is masculine singular.

In many cases, Portuguese sounds more natural with the article before nouns, especially when talking about something specific or understood in context.

Repertório literally means repertoire, but the most natural English equivalent depends on context.

It can refer to:

• a set of songs
• a performance selection
• a program of material
• sometimes something like a setlist, depending on the situation

So although repertoire is the direct translation, learners should know the practical meaning can vary a little depending on whether the context is music, theater, dance, or something similar.

Because Portuguese usually contracts the preposition em with the definite article.

• em + a = na
• em + o = no
• em + as = nas
• em + os = nos

So:

• entramos em a cabine is not the normal form
• entramos na cabine is the correct contracted form

This is one of the most important contraction patterns in Portuguese.

Cabine is a feminine noun in Portuguese.

That is why it takes:

• a cabine = the booth/cabin
• na cabine = in the booth/cabin

If it were masculine, you would expect o and no instead.

For example:

• no carro = in the car
• na cabine = in the booth

Yes.

Just like escolhemos, entramos can mean either:

• we enter / we are entering in some present-time contexts
• we entered in the preterite

In this sentence, it clearly means we entered, because it follows another completed event in the past.

So both main verbs in the sentence are forms that depend on context for interpretation.

Because the sentence narrates two completed actions in sequence:

1. we chose the repertoire
2. we entered the booth

The preterite is the normal tense for completed events that move the story forward.

So:

• escolhemos = completed action
• entramos = completed action

This is very common in storytelling and narration.

Yes, absolutely.

That version is also natural and means essentially the same thing:

• Depois que escolhemos o repertório, entramos na cabine.
• Depois de escolhermos o repertório, entramos na cabine.

The difference is grammatical structure:

• depois que + conjugated verb
• depois de + infinitive / personal infinitive

Because the subject is we, Portuguese often uses the personal infinitive:

• depois de escolhermos

Both are correct and natural.

This is about mood and time reference.

• depois que escolhemos refers to a completed event in the past: after we chose
• depois que escolhermos refers to the future: after we choose

So:

• Depois que escolhemos o repertório, entramos na cabine. = past sequence
• Depois que escolhermos o repertório, entraremos na cabine. = future sequence

In other words, escolhemos is indicative because the choosing already happened, while escolhermos would be used for a future situation.

Yes. Portuguese allows some flexibility.

For example, you could also say:

• Entramos na cabine depois que escolhemos o repertório.

This has the same basic meaning.

The original version puts the after clause first, which helps present the timeline clearly:

• first choosing
• then entering

Putting the time clause first is very common and natural.

In natural speech, the words flow together smoothly.

A rough idea:

• que is often pronounced like kee or a reduced ki
• escolhemos sounds roughly like es-ko-LYE-mos in many learner-friendly approximations

When spoken together, Brazilians do not pause much between them:

• depois que escolhemos...

The que links directly into escolhemos, and the whole phrase is said as one rhythmic unit rather than as separate word-by-word pieces.

Not always.

Cabine can mean different things depending on context, such as:

• booth
• cabin
• compartment
• stall, in some settings

So the best translation depends on the situation. If the scene is a recording studio, radio station, voting station, photo booth, or another enclosed small space, booth may be the best choice. In other contexts, cabin or compartment might fit better.
