You probably don't think of this much in the context of autumn and fall and October, however, I think it a perfect fit for some of the melancholy many feel about this time--it's a great song for the falling of the leaves.
Music when Soft Voices Die (To --)
Percy Bysshe ShelleyMusic, 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 heaped for the belovèd's bed;
And so thy thoughts, when thou art gone,
Love itself shall slumber on.
