Điệp khúc ở đây.

Điệp khúc usually means chorus or refrain, especially in music or song lyrics.

• điệp suggests repetition
• khúc can mean a section or piece

So together, điệp khúc is the repeated section of a song.

Ở đây means here or more literally at here / in this place.

• ở = at, in, located at
• đây = here, this place

In many cases, English just says here, but Vietnamese often uses ở đây to express location clearly.

Vietnamese often leaves out the verb to be when talking about location.

So where English says:

• The chorus is here

Vietnamese can simply say:

• Điệp khúc ở đây

This is completely normal.
You do not need là here.

You usually would not use là in a basic location sentence.

• A ở B = A is at/in B

So:

• Điệp khúc ở đây = natural
• Điệp khúc là ở đây = unnatural in most normal contexts

The word là is mainly used for:

• identification: Đây là điệp khúc = This is the chorus
• definitions / equivalence
• emphasis in some special structures

But for simple location, just use ở.

Vietnamese commonly puts the thing first, then its location:

• điệp khúc = the chorus
• ở đây = here

So the pattern is:

• subject/topic + location

This matches a very common Vietnamese structure:

• Sách ở đây = The book is here
• Anh ấy ở nhà = He is at home

Yes, but it changes the feel and structure.

• Điệp khúc ở đây = The chorus is here
• Ở đây là điệp khúc = more like Here is the chorus or This part here is the chorus

The second version is more marked and can sound like you are pointing something out or identifying a section. It is not the most neutral version.

Sometimes đây alone is possible, but ở đây is clearer and more standard for location.

Compare:

• Điệp khúc đây — not very natural in most everyday situations
• Điệp khúc ở đây — natural for saying where it is

So for learners, ở đây is the safer choice when you mean here as a location.

It can be a complete sentence, but depending on context, it may sound a bit short or clipped.

For example, it could be used:

• while pointing at a place in lyrics
• in music discussion
• as a note in teaching or editing

In natural conversation, people might often say something a little fuller, such as:

• Điệp khúc ở đây nè.
• Đây là điệp khúc.
• Điệp khúc bắt đầu ở đây.

So Điệp khúc ở đây is grammatical, but context matters.

A rough guide:

• điệp: sounds somewhat like yip with a falling/heavy tone
• khúc: roughly khook with a rising-sharp tone
• ở: a short vowel somewhat like a central vowel, with a broken-rising tone in northern speech
• đây: roughly day with a level or mid tone

A few important points:

• đ is pronounced like English d
• kh is like the ch in German Bach or Scottish loch, not like English k
• tones matter a lot, especially in điệp, khúc, and ở

It is written as two words, but it functions as a single fixed expression meaning chorus / refrain.

This is very common in Vietnamese: many compounds are written with spaces between syllables, even though they form one lexical unit.

So you should learn điệp khúc as one vocabulary item.
