Detén la música.

Detén is the affirmative informal singular command of detener.

So it is the form you use when you are telling one person you address as tú to stop something.

• detener = to stop
• detén = stop! (to one person, informal)

In this sentence, Detén la música, the speaker is giving a direct command.

Because Spanish commands do not always use the normal present-tense tú form.

For the verb detener, the normal tú present form is:

• tú detienes = you stop

But the affirmative tú command is:

• detén = stop!

This verb is irregular because detener belongs to the tener family:

• tener → ten
• detener → detén

So detén is something you need to learn as a special command form.

The accent mark shows where the stress goes: de-TÉN.

Without the accent, Spanish spelling rules would normally make you stress it differently. Since the stress falls on the last syllable, the written accent is needed.

So:

• detén = correct
• stress: de-TÉN

It is informal, because detén is the tú command.

If you wanted to speak more formally to one person, you would say:

• Detenga la música.

Other useful command forms are:

• Detén la música. = informal singular
• Detenga la música. = formal singular
• Detened la música. = informal plural in Spain (vosotros)
• Detengan la música. = formal plural / Latin American plural

Because Spanish often uses the definite article where English may not.

Here, la música means the music, referring to the music that is playing or the music already understood from context.

• Detén la música = Stop the music.

Saying Detén música sounds unnatural in normal Spanish.

Yes. Música is a feminine noun, so it takes:

• la música

If you use adjectives with it, they must also agree in the feminine form:

• la música alta = the loud music

So in the sentence, la is there because música is feminine singular.

Yes. Para la música is also very natural and common.

Both mean Stop the music, but there is a slight difference in feel:

• parar is very common in everyday speech for stop
• detener can sound a bit more forceful, formal, or literal depending on context

In many everyday situations, a Spanish speaker might be more likely to say:

• Para la música.

But Detén la música is still perfectly correct.

Because la música is the direct object of detener.

In this sentence, the action goes directly onto the thing being stopped:

• stop the music

So Spanish says:

• Detén la música

not:

• Detén a la música
• Detén de la música

No preposition is needed here.

You would say:

• No detengas la música.

This is important because negative commands use a different form from affirmative tú commands.

Compare:

• Detén la música. = Stop the music.
• No detengas la música. = Don’t stop the music.

So the affirmative and negative forms are not built the same way.

You can replace la música with a pronoun:

• Detenla. = Stop it.

Here la means it, referring to la música.

A useful rule:

• in affirmative commands, pronouns attach to the end
• in negative commands, pronouns go before the verb

So:

• Detenla. = Stop it.
• No la detengas. = Don’t stop it.

A simple pronunciation guide is:

• de-TEN la MOO-see-ka

More closely:

• detén → stress on the last syllable
• música → stress on the first syllable: MÚ-si-ca

So the rhythm is:

• de-TÉN la MÚ-si-ca

In standard Spain Spanish, the s sound here is a normal s, not the th sound, because there is no z or soft c in this sentence.

In this sentence, it usually means the music that is currently playing, so it feels specific because of the situation.

Depending on context, it might refer to:

• a song
• some background music
• the music in a room, car, or event

So la música does not have to mean one exact song. It means the music that both speaker and listener understand from the context.
