Il video ha una traccia musicale.

In Italian, nouns usually need an article more often than in English. Here il video means the video and refers to a specific video.

Also, il is the correct masculine singular article before a noun that starts with most consonants, including v:

• il video
• il libro
• il film

Ha is the third-person singular form of avere (to have): he/she/it has.

The h is silent. It is written to distinguish the verb form ha from the preposition a (to, at).

Examples:

• Il video ha una traccia musicale. = The video has a music track.
• Vado a Roma. = I’m going to Rome.

Yes, video is masculine in Italian, so it takes il in the singular:

• il video

Its standard plural is usually i video. The word is commonly treated as invariable, so the singular and plural look the same:

• il video
• i video

Because traccia is a feminine singular noun that begins with a consonant.

Use:

• una before most feminine singular nouns beginning with a consonant
• un' before feminine singular nouns beginning with a vowel

So:

• una traccia
• una casa
• un'amica
• un'idea

Here traccia musicale means a music track or musical track. In context, it usually refers to an audio track containing music.

The noun traccia can have several meanings in Italian depending on context, such as:

• track
• trace
• clue
• trail

But in this sentence, because of musicale, the meaning is clearly related to audio/music.

In Italian, adjectives often come after the noun, especially when they are simply describing it in a straightforward way.

So:

• traccia musicale = musical/music track
• libro interessante = interesting book
• film italiano = Italian film

That is the normal word order here.

Good question. Some Italian adjectives have the same form for masculine singular and feminine singular. Musicale is one of them.

So you get:

• traccia musicale = feminine singular
• video musicale = masculine singular

The adjective changes only in the plural:

• tracce musicali
• video musicali

Traccia is pronounced approximately TRAH-chah.

A few useful points:

• tr sounds like in English track
• ccia here sounds like cha
• the stress is on the first syllable: TRAC-cia

So the whole sentence is approximately:

Il VIDEO ha una TRAC-cia musi-CA-le.

Yes. Depending on context, Italians might also say:

• colonna sonora = soundtrack
• musica di sottofondo = background music
• traccia audio = audio track

But traccia musicale is perfectly understandable and natural for music track.

You would say:

I video hanno tracce musicali.

Here is what changed:

• il → i
• ha → hanno
• una traccia → tracce
• musicale → musicali

So the sentence becomes The videos have music tracks.
