This morning the music of a brass band which had stopped under my windows moved me almost to tears. It exercised an indefinable, nostalgic power over me; it set me dreaming of another world, of infinite passion and supreme happiness. Such impressions are the echoes of Paradise in the soul; memories of ideal spheres whose sad sweetness ravishes and intoxicates the heart. O Plato! O Pythagoras! ages ago you heard these harmonies, surprised these moments of inward ecstasy, — knew these divine transports! If music thus carries us to heaven, it is because music is harmony, harmony is perfection, perfection is our dream, and our dream is heaven.
