O sole mio! was composed in 1898. I can say it is the most famous Italian song or it’s better to say the most famous Neapolitan song in history.
Lyrics by Giovanni Capurro (Italian poet)
Music by Eduardo Di Capua (an Italian composer,singer)
When Eduardo Di Capua composed the music for O sole mio! he was in Odessa (Ukraine). Maybe that influenced the strong feeling of the song? When you hear this piece, you may feel the joy or a nostalgia for a beautiful sunny day….
