My mom is a never-ending song in my heart of comfort, happiness, and being. I may sometimes forget the words but I always remember the tune.

The speaker frames maternal love as music: continuous, internal, and sustaining. “Never-ending song” suggests a presence that persists beyond physical proximity or even beyond memory’s precision. Forgetting “the words” evokes the way specific moments, advice, or details of a mother’s care can fade with time, distance, or grief; yet remembering “the tune” implies that the emotional pattern—comfort, happiness, a sense of self (“being”)—remains ingrained. The metaphor emphasizes how foundational relationships become part of one’s inner life: not always consciously recalled in exact form, but reliably felt as a guiding rhythm that steadies and consoles.
