Ludovico Einaudi made the "Ascolta (Instrumental)" composition. It starts with the major notes, immediately brings sadness and makes us closer to eternity. If this was the purpose of this melody, then, of course, it had performed one. Notes of piano beautifully complemented by background sounds. Melody is the sad on nature, because you expect exactly like this from really powerful instrumental melodies.
