Because there are two separate objects in the sentence:

• 창문을 열고 = open the window
• 음악을 들어요 = listen to music

In Korean, 을/를 marks the object of a verb.

• 창문을: window is the object of 열다 (to open)
• 음악을: music is the object of 듣다 (to listen)

So the sentence is really:

• 창문을 열고 = opening the window
• 음악을 들어요 = listening to music

English uses word order to show this, but Korean often uses particles.

-고 is a very common connector that means and.

Here:

• 열다 = to open
• 열고 = open and / opening and

So:

• 창문을 열고 음악을 들어요 = I open the window and listen to music

In this sentence, -고 connects two actions:

1. open the window
2. listen to music

It often suggests that the actions happen in sequence, especially when that makes sense naturally, but its basic job is just to connect verbs.

This is because 듣다 is an irregular verb.

The dictionary form is:

• 듣다 = to listen

When you add -어요, the ㄷ changes to ㄹ before a vowel:

• 듣다 → 들어요

So it is not:

• 듣어요 ✘

It is:

• 들어요 ✔

This happens with some Korean verbs that have final ㄷ in the stem.

A similar example:

• 걷다 = to walk
• 걸어요 = walk / am walking

So 들어요 is the correct polite present form of 듣다.

The two verbs are:

• 열고 → from 열다 = to open
• 들어요 → from 듣다 = to listen

How they are built:

• 열다 → remove 다 → 열- → add -고 → 열고
• 듣다 → irregular change → 들- → add -어요 → 들어요

So the sentence uses:

• one verb in a connecting form: 열고
• one verb in a polite ending: 들어요

This is very common in Korean: earlier verbs get a connector, and the final verb carries the tense/politeness ending.

Because Korean is usually a subject-object-verb language.

English often uses:

• I open the window and listen to music.

Korean tends to put the verb after the object:

• 창문을 열고 음악을 들어요

A rough word-by-word order is:

• window + object marker + open-and + music + object marker + listen

The final verb is especially important because it completes the sentence.

This word order can feel unusual to native English speakers at first, but it is one of the most basic patterns in Korean.

The subject is omitted.

This is extremely common in Korean. If the subject is clear from context, Korean often leaves it out.

So this sentence could mean:

• I open the window and listen to music.
• He/She opens the window and listens to music.
• They open the window and listen to music.

The exact subject depends on the situation.

If you wanted to include it, you could say:

• 저는 창문을 열고 음악을 들어요. = I open the window and listen to music.

But in everyday Korean, leaving out the subject is very natural.

-어요 shows that the sentence is in a polite informal style (often called the 해요 style).

So 들어요 is a polite way to say:

• listen
• am listening
• listen habitually

Depending on context, Korean present tense can cover several English meanings, such as:

• I listen to music
• I am listening to music
• I listen to music regularly

The sentence ending -어요 is very common in everyday conversation because it is polite without being too formal.

Usually, yes, it naturally suggests:

1. open the window
2. listen to music

But -고 itself is a fairly neutral and connector. Its main role is to link actions, not strongly emphasize timing.

In real usage, listeners often understand the order from common sense. Since you would normally open the window first and then listen to music, that is the most natural interpretation.

So the sentence is best understood as:

• Open the window and then listen to music or
• I open the window and listen to music

depending on context.

Yes. 음악을 듣다 is the standard expression.

• 음악 = music
• 듣다 = to listen
• 음악을 듣다 = to listen to music

This can feel different from English because English uses listen to with a preposition, while Korean uses a verb that directly takes an object with 을/를.

So English:

• listen to music

Korean:

• music + object marker + listen

That is completely normal in Korean.

Yes. Korean present tense often covers both:

• what someone is doing now
• what someone does regularly

So 창문을 열고 음악을 들어요 could mean:

• I open the window and listen to music right now or
• I usually open the window and listen to music

Context tells you which meaning is intended.

If the speaker wants to make the right now meaning especially clear, they may add time words or context. But by itself, the sentence can work for either.
