Il coro prova stasera.

Il is the masculine singular definite article, meaning the.

So:

• il coro = the choir

In Italian, articles are used more often than in English, so a noun like coro will usually need an article unless the context clearly calls for no article.

Also, coro is a masculine singular noun, which is why it takes il.

Coro means choir or chorus.

A few useful related words:

• il coro = the choir
• i cori = the choirs / choruses

Even though a choir is made up of many people, the noun itself is grammatically singular, so it takes a singular verb here.

Here, prova is a verb.

It comes from provare, and in this sentence it is the third-person singular present tense:

• io provo = I rehearse / I try
• tu provi = you rehearse / you try
• lui/lei prova = he/she rehearses / tries

Since the subject is il coro (singular), the verb is prova.

This can be confusing because prova can also be a noun, meaning things like:

• test
• attempt
• rehearsal

But in Il coro prova stasera, it is clearly being used as a verb because the structure is:

• subject + verb + time expression

Yes, provare often means to try, but it has several meanings depending on context.

Common meanings include:

• to try
• to test
• to feel (an emotion)
• to rehearse

With performers such as a choir, band, orchestra, or actors, provare often means to rehearse.

For example:

• Il coro prova = The choir rehearses
• L’orchestra prova = The orchestra rehearses

So the context tells you which meaning is intended.

Stasera means tonight / this evening, and it functions as a time expression.

It is commonly written as one word:

• stasera

You may also see:

• questa sera

These are very close in meaning. In many everyday situations, they are interchangeable.

In the sentence, stasera tells you when the action happens:

• Il coro prova stasera. = The choir rehearses tonight.

Because stasera already works as an adverbial time expression, like tonight in English.

So Italian says:

• prova stasera = rehearses tonight

not:

• prova a stasera
• prova in stasera

This is normal with many common time expressions in Italian, such as:

• oggi = today
• domani = tomorrow
• stasera = tonight

Italian often uses the present tense for a future event when the time is already clear from the context.

Here, stasera makes the time clear, so prova can naturally mean:

• rehearses tonight
• is rehearsing tonight
• will rehearse tonight

This is very common in both Italian and English.

Compare:

• Parto domani. = I’m leaving tomorrow.
• Il coro prova stasera. = The choir rehearses tonight.

Yes. Italian word order is flexible, although Il coro prova stasera is the most neutral order.

You could also say:

• Stasera il coro prova.

This puts more emphasis on stasera.

Both are correct, but they may sound slightly different in focus:

• Il coro prova stasera. = neutral statement
• Stasera il coro prova. = emphasis on tonight

A simple pronunciation guide is:

• il KOH-roh PROH-va sta-SEH-ra

A few notes:

• coro: the c is a hard k sound before o
• prova: open, clear vowels
• stasera: the stress is on -se-

So:

• il KOH-roh PROH-va sta-SEH-ra

Yes. You can say:

• Il coro prova stasera.
• Il coro prova questa sera.

Both are natural and correct.

In many contexts:

• stasera is slightly more compact and conversational
• questa sera can sound a bit fuller or more explicit

But the meaning is essentially the same.
