• That was the first sound in the song of love!
    Scarce more than silence is, and yet a sound.
    Hands of invisible spirits touch the strings
    Of that mysterious instrument, the soul,
    And play the prelude of our fate. We hear
    The voice prophetic, and are not alone.

    Henry Wadsworth Longfellow (1872). “The poetical works of Henry Wadsworth Longfellow. Author's complete ed”, p.108
