Imperfetto vs Passato Prossimo
The imperfetto and passato prossimo are often used together in past narrations.
They express different kinds of actions in the past and cannot be used interchangeably.
1. The Imperfetto describes situations and tells what used to happen.
Ieri ero triste.
Yesterday I was sad.
Quando ero un bambino andavo spesso alla spiaggia.
When I was a child I used to go to the beach.
2. The passato prossimo lists facts and events.
Ieri ho telefonato a un' amica.
Yesterday I called a friend.
Un giomo sono andato in montagna.
One day I went to the mountains.
3. The imperfetto expresses unfinished actions in the past.
Ieri alle dieci dormivo già.
Yesterday at ten I was already sleeping.
4. The passato prossimo expresses finished actions in the past.
Ieri ho dormito fino alle dieci.
Yesterday I slept until ten.
Sono arrivata il 10 agosto.
I arrived August tenth.
5. The passato prassimo expresses what happened at a certain moment, whereas the imperfetto expresses a state or a habit. Therefore the passato prossimo is the tense used to indicate a change in a state.

We were playing soccer when it started to rain.
Guardavamo la TV quando il telefono è suonato.
