Απόψε θα ακούω μουσική όλη τη βραδιά.

Απόψε means tonight.

It is a single adverb, and it is very commonly used in everyday Greek. It is close in meaning to σήμερα το βράδυ (this evening / tonight), but απόψε is shorter and often sounds more natural when you just want to say tonight.

So:

• Απόψε θα ακούω μουσική. = Tonight I’ll be listening to music.
• Σήμερα το βράδυ θα ακούω μουσική. = also correct, but a bit more expanded.

This is one of the most important Greek aspect differences.

• θα ακούω = imperfective future
• θα ακούσω = perfective future

In this sentence, θα ακούω is used because the action is seen as ongoing over a period of time: all evening.

So:

• θα ακούω μουσική όλη τη βραδιά = I’ll be listening to music all evening
• θα ακούσω μουσική = I’ll listen to music / I’ll hear some music (more like a single event or a complete action)

Because the sentence includes όλη τη βραδιά (all evening), the continuous/ongoing form θα ακούω fits very well.

Yes, ακούω is the present/imperfective non-past form of the verb to listen / hear.

By itself:

• Ακούω μουσική. = I listen to music / I am listening to music

When you add θα, it becomes future:

• Θα ακούω μουσική. = I will be listening to music

So Greek does not make the future by changing the verb ending the way English sometimes does. Instead, it usually uses θα + verb.

Greek often leaves out the subject pronoun because the verb ending already tells you who the subject is.

Here, ακούω means I listen / I am listening, so I is already built into the verb.

That means:

• Θα ακούω μουσική = I will be listening to music
• Εγώ θα ακούω μουσική = also correct, but now εγώ adds emphasis, like I will be listening to music

So the version without εγώ is the normal neutral one.

Because here μουσική is being used in a general sense: music as a thing or activity, not a specific piece of music.

So:

• ακούω μουσική = I listen to music
• ακούω τη μουσική = I listen to the music (specific music)

English does the same thing:

• I listen to music
• I listen to the music

So the Greek sentence sounds natural without the article.

It expresses duration of time: for the whole evening / all evening.

Grammatically, it is in the accusative, which is normal in Greek for many time expressions.

Breakdown:

• όλη = whole / all
• τη = short form of την, the feminine accusative article
• βραδιά = evening

So όλη τη βραδιά literally means something like the whole evening.

In this sentence, it functions adverbially: it tells you for how long the action happens.

Both are correct.

την is the full form of the feminine accusative article, but in modern Greek the final -ν is often dropped before certain consonants.

So:

• όλη την βραδιά
• όλη τη βραδιά

Both mean the same thing. The shorter form τη is very common and natural.

They are related, and in many contexts both can refer to evening / night, but they are not always felt exactly the same way.

Very roughly:

• βράδυ = the evening/night period in a more neutral, everyday sense
• βραδιά = the evening as a stretch of time or occasion; sometimes it can feel a bit more like the evening experience

So this sentence could also be said as:

• Απόψε θα ακούω μουσική όλο το βράδυ.

That version may sound even more everyday to some speakers. But όλη τη βραδιά is also perfectly understandable and natural.

Yes. Greek word order is more flexible than English word order.

The given sentence:

• Απόψε θα ακούω μουσική όλη τη βραδιά.

is very natural because it starts with the time word Απόψε and sets the scene right away.

Other possible orders are:

• Θα ακούω μουσική όλη τη βραδιά απόψε.
• Μουσική θα ακούω απόψε όλη τη βραδιά.

But these may sound different in emphasis. The original version is a neutral, smooth way to say it.

With θα ακούω, the focus is on the action as ongoing or in progress. In this sentence, because of Απόψε and όλη τη βραδιά, most people will understand it as one continuous activity during tonight.

So the most natural interpretation is:

• Tonight I’ll be listening to music all evening.

In other contexts, θα ακούω can also describe something habitual or repeated in the future, but here the time phrases make it sound like one evening-long situation.

A very common alternative would be:

• Απόψε θα ακούω μουσική όλο το βράδυ.

This means essentially the same thing and may sound slightly more conversational to many speakers.

Another possible version is:

• Απόψε θα ακούσω μουσική.

But that changes the meaning a bit: it no longer emphasizes all evening or the ongoing nature of the action.

So if you want the idea of spending the whole evening listening to music, the original sentence works well.
