I tenori coordinano le voci e la respirazione.

In this sentence, I is not the pronoun they. It is the masculine plural definite article, meaning the.

So:

• i tenori = the tenors

Italian has several different words for the, depending on gender and number:

• il = masculine singular
• i = masculine plural
• la = feminine singular
• le = feminine plural

Here, tenori is masculine plural, so i is the correct article.

Tenore is singular: tenor.
Tenori is plural: tenors.

This follows a very common Italian pattern:

• masculine singular nouns ending in -e
• form the plural in -i

So:

• il tenore = the tenor
• i tenori = the tenors

Coordinano is the third-person plural form of the verb coordinare, meaning to coordinate.

So:

• coordino = I coordinate
• coordini = you coordinate
• coordina = he/she coordinates
• coordiniamo = we coordinate
• coordinate = you all coordinate
• coordinano = they coordinate

Because the subject is i tenori (the tenors), the verb must also be plural:

• I tenori coordinano = The tenors coordinate

Voci is the plural of voce, which means voice.

• la voce = the voice
• le voci = the voices

Since voce is a feminine noun, its plural article is le.

So:

• le voci = the voices

Also note the plural change:

• nouns ending in -e often become -i in the plural
• voce is a little special in spelling because it becomes voci, not vocei

Because respirazione here is being treated as a general activity or process, so Italian naturally uses the singular:

• la respirazione = breathing / respiration

This is very common. English also often uses a singular abstract noun in the same way:

• coordinate the voices and breathing

So the sentence combines:

• le voci = the voices
• la respirazione = breathing / respiration

One is plural because it refers to multiple voices; the other is singular because it refers to the general act or process of breathing.

Italian uses definite articles more often than English does.

In English, you might say:

• Tenors coordinate voices and breathing

But in Italian, it is usually more natural to say:

• I tenori coordinano le voci e la respirazione

Italian often prefers articles with nouns, especially when talking about categories, body-related functions, or things understood in a general but definite way.

So even if English may leave out the, Italian often keeps it.

Yes, this sentence has a very straightforward word order:

• I tenori = subject
• coordinano = verb
• le voci e la respirazione = object

So it follows the same basic pattern as English:

• The tenors coordinate the voices and the breathing

Italian word order can be more flexible than English, but this sentence uses the standard and most natural order.

There are two main clues:

1. The article and noun at the start

   • I tenori clearly forms a noun phrase: the tenors

2. The verb ending

   • coordinano is a third-person plural verb form, so it matches a plural subject
   • tenori is plural, so it fits perfectly

So the sentence structure is clearly:

• I tenori = subject
• coordinano = verb

In most normal contexts, no. That would sound incomplete or unnatural in standard Italian.

Italian usually needs an article before a plural count noun like this when you mean the tenors as a group:

• I tenori coordinano... = correct

Without the article:

• Tenori coordinano... = generally not natural here

You might see article omission in special contexts such as headings, labels, or very compressed style, but not in an ordinary sentence like this.

Because Italian usually does not need subject pronouns when the verb ending already shows who is doing the action.

Here, coordinano already means they coordinate, so Italian can simply say:

• I tenori coordinano...

The noun i tenori already tells you who they are, so adding loro would usually be unnecessary.

It is pronounced roughly like:

• koh-or-DEE-nah-no

A few helpful points:

• co- sounds like ko
• or is a clear rolled or tapped r sound in careful speech
• stress falls on na? Actually in coordinano, the stress falls on di: co-or-DI-na-no
• all vowels are pronounced clearly

A more careful breakdown:

• co-or-di-na-no

Italian pronunciation is usually very regular, so each written vowel is pronounced.

It is closely related, but in many everyday contexts respirazione can sound more natural as breathing rather than the more technical English word respiration.

So depending on context, it could be understood as:

• respiration
• breathing

In a musical or vocal context, English often prefers breathing.

Because grammatical gender in Italian is a property of the noun itself, and it does not always match natural gender or English logic.

In this sentence:

• tenore is masculine
• voce is feminine
• respirazione is feminine

That is why the articles change:

• i tenori
• le voci
• la respirazione

You usually have to learn each noun together with its article, because gender affects articles, adjectives, and sometimes pronouns.

Here are the singular forms:

• i tenori → il tenore
• le voci → la voce
• coordinano → coordina if the subject is singular
• la respirazione stays singular already

So a singular version of the sentence would be:

• Il tenore coordina la voce e la respirazione.

That would mean The tenor coordinates the voice and the breathing/respiration.

Yes, it can, depending on context.

Italian definite articles are often used where English may use either:

• the tenors or
• tenors in a general/class sense

So I tenori coordinano le voci e la respirazione could refer to:

• a specific group of tenors, or
• tenors as a category in a general statement

Context usually tells you which meaning is intended.
