There is nothing in the world of art like the songs mother used to sing.

The line elevates domestic, remembered music—especially a mother’s songs—above formal “art,” suggesting that emotional truth and formative influence can outweigh aesthetic sophistication. In Sunday’s moral universe, the mother figure often represents early religious instruction, tenderness, and the shaping of conscience; “songs mother used to sing” can imply hymns or simple household melodies that carry spiritual and ethical memory. The quote thus works as a defense of sentiment and piety against worldly entertainments: what endures is not virtuosity or fashionable culture, but the intimate art that binds family, faith, and childhood experience.
