무슨 means what or what kind of. In this sentence, it is asking about the type of music someone listens to.

So 무슨 음악 means what music or more naturally in English, what kind of music.

을 is the object particle. It marks 음악 as the thing being listened to.

• 음악 = music
• 음악을 = music + object marker

Since 듣다 means to listen to / to hear, it takes an object, so 을/를 is used.

This is because 듣다 is an irregular ㄷ verb.

Here is what happens:

• dictionary form: 듣다
• stem: 듣-
• when a vowel beginning ending is added, the ㄷ changes to ㄹ
• so 듣 + 어요 becomes 들어요

This is a very common pattern with some Korean verbs.

It often translates as listen to, but it can also mean hear depending on context.

In 무슨 음악을 들어요?, the natural English meaning is What kind of music do you listen to?

Because the object is music, English usually uses listen to here.

Korean often leaves out the subject when it is obvious from context.

So 무슨 음악을 들어요? literally looks like What music listen?, but the listener understands that it means:

• What kind of music do you listen to?

In conversation, omitting subjects is very normal in Korean.

들어요 is the polite casual or standard polite style, often called -아요/어요 style.

It is polite and very common in everyday conversation. You can use it with:

• people you do not know well
• classmates
• coworkers
• most everyday situations

It is less formal than 듣습니까? and more polite than plain 들어?

A natural pronunciation is close to:

무슨 → 무슨
음악을 → 으마글
들어요 → 드러요

So the whole sentence sounds roughly like:

무슨 으마글 드러요?

This happens because Korean pronunciation changes naturally in connected speech.

Yes, in casual spoken Korean, particles like 을/를 are often dropped.

So both are possible:

• 무슨 음악을 들어요?
• 무슨 음악 들어요?

The version with 을 is more complete and clearer grammatically, while the version without it sounds natural in conversation.

Korean usually follows Subject-Object-Verb order.

So this sentence is structured like this:

• 무슨 = what kind of
• 음악을 = music + object marker
• 들어요 = listen

Literally: What kind of music do-listen?

Since the verb comes at the end in Korean, this is normal word order.

Yes, you can, and it is very similar.

• 무슨 음악을 들어요? = What kind of music do you listen to?
• 어떤 음악을 들어요? = What kind of music do you listen to?

In many situations, they are interchangeable.

A small nuance:

• 무슨 can feel a bit more like what
• 어떤 can feel a bit more like what kind of / which sort of

But in this sentence, both are very natural.

You can change the ending:

• 무슨 음악을 들어? = casual, used with close friends or someone younger
• 무슨 음악을 들어요? = polite everyday style
• 무슨 음악을 들으세요? = more polite, respectful
• 무슨 음악을 듣습니까? = formal

So the core meaning stays the same, but the ending changes depending on who you are talking to.
