This is a really pretty Italian lullaby. Italian is a beautiful sounding language. It is lyrical and expressive, and because of that, it has been used for the lyrics in music for centuries.
Once, I was walking through an airport in Rome, Italy with my brother and there was an announcement in Italian. Probably something like, “Flight 22 is leaving from gate 7 in 5 minutes. Hurry up or you’ll miss your flight!” and my brother looked at me and said, “that sounded like a song” and he was right. Italian is so beautiful that it makes an airport announcement sound pretty, like a song.
