Lời bài hát ở dưới khuông nhạc.

Lời bài hát means the lyrics of the song or simply song lyrics.

Breakdown:

• lời = words, wording, lyrics
• bài hát = song

So literally, it is something like the words of the song.

Because bài hát means the song itself, while lời bài hát specifically means the lyrics.

Compare:

• bài hát = song
• lời bài hát = song lyrics

So if you say Lời bài hát ở dưới khuông nhạc, you are talking about where the lyrics are placed, not where the whole song is.

Here, ở marks location. It is very common in Vietnamese when saying where something is.

In this sentence:

• ở dưới = is below / is underneath

So ở helps express the idea of being in a place.

You can think of the structure as:

• [thing] + ở + [location]

Example:

• Cuốn sách ở trên bàn. = The book is on the table.
• Lời bài hát ở dưới khuông nhạc. = The lyrics are below the musical staff.

Often, dưới can appear by itself in some contexts, but ở dưới is a very common and natural way to express location.

• dưới = under, below
• ở dưới = located below / down below

Using ở makes the location relationship clearer and more sentence-like.

So:

• Lời bài hát dưới khuông nhạc may sound incomplete or less natural in many contexts
• Lời bài hát ở dưới khuông nhạc sounds like a full statement: The lyrics are below the staff

Khuông nhạc means musical staff or stave: the set of horizontal lines used in written music.

So:

• dưới khuông nhạc = below the staff

If you are looking at printed music, this sentence means the lyrics are written underneath the staff lines.

Vietnamese often uses this basic order:

• subject + location phrase

So here:

• Lời bài hát = the lyrics
• ở dưới khuông nhạc = are below the staff

That gives:

• Lời bài hát ở dưới khuông nhạc.

This is very similar to English:

• The lyrics are below the staff.

Vietnamese usually does not rearrange this into an English-style question of word order unless there is a special emphasis or different structure.

Not exactly a hidden word, but Vietnamese does not always use a direct equivalent of English to be the same way English does.

In location sentences, ở often does the job of showing where something is.

So instead of thinking:

• lyrics + are + below the staff

it is better to think:

• lyrics + located at below the staff

That is why the sentence works naturally without a separate word exactly like English are.

Yes, that is possible.

• ở dưới = is below
• nằm dưới = lies below / is situated below

nằm can make the sentence sound a bit more descriptive, as if you are talking about physical placement on a page.

So both can work:

• Lời bài hát ở dưới khuông nhạc.
• Lời bài hát nằm dưới khuông nhạc.

The version with ở is straightforward and very common for basic location.

Vietnamese does not use articles like English a, an, and the in the same way.

So khuông nhạc can mean:

• a musical staff
• the musical staff

The exact meaning depends on context.

In this sentence, English may naturally translate it as the musical staff, but Vietnamese does not need a separate article word there.

They are similar, but not always identical in tone or nuance.

• ở dưới = below, underneath, in the lower position
• bên dưới = below, underneath, often a bit more explicitly spatial

You could also hear:

• Lời bài hát ở bên dưới khuông nhạc.

That is also natural and may sound slightly fuller or more specific. But ở dưới is perfectly normal here.

A careful pronunciation would be something like:

• Lời — rising tone
• bài — falling tone
• hát — sharp rising checked tone
• ở — open vowel with a falling-rising tone
• dưới — falling-rising tone
• khuông — level tone
• nhạc — low checked tone

A natural rhythm is:

Lời bài hát | ở dưới | khuông nhạc.

Learners often need to watch out especially for:

• lời vs lời
• dưới
• nhạc

because the vowel quality and tones can be difficult if you are coming from English.

Yes. It is natural and clear, especially in a teaching or descriptive context, such as talking about sheet music.

It sounds like the speaker is describing the layout of music notation:

• the staff is on top
• the lyrics are underneath

A native speaker might also say:

• Lời bài hát được viết dưới khuông nhạc. = The lyrics are written below the staff.
• Lời bài hát nằm dưới khuông nhạc. = The lyrics are below the staff.

But your original sentence is completely fine.
