Very well done. Throughout a similarity chain it goes from the Enel (The Italian state supplier of electric power) to the music.

The starting point is central: The electric lamp with its filament built in form of two musical notes.

Going to the right side, we have: The electric lamp -> its filament -> musical notes -> music.

Going to the left side, we have: The electric lamp -> electricity -> power -> Enel.

Writing within the image: L' ENERGIA CHE SI ASCOLTA (the power we are listening to). The Enel, as Energiaper, is the sponsor of musical events of and of the Accademia Nazionale di Santa Cecilia and of the Teatro alla Scala.

This is the top of simplicity and of ability to communicate.
