in Thoreau’s Journal:
I hear a cricket creak in the shade; also the sound of a distant piano. The music reminds me of imagined heroic ages; it suggests such ideas of human life and the field which it affords as the few noblest passages of poetry. Those few interrupted strains which reach me through the trees suggest the same thoughts and aspirations that all melody, by whatever sense appreciated, has ever done. I am affected. What coloring variously fair and intense our life admits of! How a thought will mould and paint it. Impressed by some vague vision, as it were, elevated into a more glorious sphere of life, we no longer know this, and we can deny its existence. We say we are enchanted, perhaps. But what I am impressed by is the fact that this enchantment is no delusion. So far as truth is concerned, it is a fact such as what we call our actual existence, but it is a far higher and more glorious fact. It is evidence of such a sphere, of such possibilities. It is its truth and reality that affect me.
A thrumming of piano-strings beyond the gardens and through the elms. At length the melody steals into my being. I know not when it began to occupy me. By some fortunate coincidence of thought or circumstance I am attuned to the universe, I am fitted to hear, my being moves in a sphere of melody, my fancy and imagination are excited to an inconceivable degree. This is no longer the dull earth on which I stood. It is possible to live a grander life here; already the steed is stamping, the knights are prancing; already our thoughts bid a proud farewell to the so-called actual life and its humble glories. Now this is the verdict of a soul in health. But the soul diseased says that its own vision and life alone is true and sane. What a different aspect will courage put upon the face of things! This suggests what a perpetual flow of spirit would produce.
