In 1955, Tolkien elaborated phonaesthetics which is the study of beautiful words regarding only the sound they make. He thought that cellar door was the most beautiful thing to hear.

Harriet was but a spoken word from the lips of no one. Her name used to fill me with happiness but now it drowns me in grief. For you see, a variable ultimately has no meaning and will disappear for no reason.

Harriet is meaningless so she went away and her name died on my lips. The beautiful sound no longer sung in the air.
