Percy Bysshe Shelley, The Complete Poems

"Music, When Soft Voices DieMusic, when soft voices die, Vibrates in the memory; Odours, when sweet violets sicken, Live within the sense they quicken. Rose leaves, when the rose is dead, Are heap'd for the belovèd's bed; And so thy thoughts, when thou art gone, Love itself shall slumber on."

"Our sweetest songs are those of saddest thought."
