Literally translated, 'Bella Ciao' means 'goodbye beautiful'.

While it was revealed in the show that Berlin and the Professor were taught the song at a young age by their grandfather, there's some history associated with the song.

Originally sung by the Italian partisans fighting fascism during World War II, the song became a revolutionary anthem at that time.

The Italian partisans were telling their loved ones goodbye as they went to battle with the Germans. And since then, it has lived on as a symbol of freedom.

Here are the lyrics of the song...

Una mattina mi son alzato

O bella ciao, bella ciao, bella ciao, ciao, ciao

Una mattina mi son alzato

E ho trovato l'invasor

... which, in English, translates to:

One morning I awakened

Oh Goodbye beautiful, Goodbye beautiful, Goodbye beautiful! Bye! Bye!

One morning I awakened

And I found the invader

There's something infectious about the song that makes us want to play and sing it on loop.
