When listening to the song the notes are soft. The set of notes repeat itself. The pattern of low to high notes continue until it escalates to a higher pitch only to go very low. The sounds flow softly like a melody.  If i listen carefully  i can hear short intervals of breaks. In the end the music fades.

I can imagine waves on the beach as they softly go towards the shore. When a huge wave crashes harshly on a rock  because the wind is too strong, i imagine the songs notes rapidly changing pitch. As the waves slowly go back to sea.. i can imagine the song gradually fading into the background.
