"Go for
a song" indicates that something is sold, bought, or acquired at an exceptionally low price, often far below its true
value, carrying an ironic or wistful tone that poets exploit in meditations on loss, devaluation, or the ephemeral nature of material worth. Its musical etymology—referring to the cheap
street songs of buskers—grounds it in aural, ephemeral art, making it especially resonant in poems about the transience of beauty, fame, or craftsmanship. In elegies for lost estates or heirlooms, the phrase underscores the pathos of undervaluation, as precious items are carelessly disposed of. Satirical poets use it to critique consumerism and the absurdities of market value, where quality bears no relation to price. The phrase also appears in narratives of
fortune reversal, where a once-wealthy character must sell possessions "for a song," marking their descent. Its verb (go) suggests
motion and departure, while "song" implies lightness and insubstantiality, combining to create an
image of value dissolving into air. Its brevity and melodic quality (assonance of 'o') lend a lyrical sorrow that fits well into
ballad stanzas.
