EXCERPT: Emily Dickinson's speaker in "There's a certain Slant of light" reveals a mood of slight melancholy as she muses on a shaft of light streaming in through her window on a winter afternoon.
That streaming light through the window seems to tip and tilt, that is, "slant," in a way that causes the speaker to undergo that sense of melancholy, which is no ordinary gloom but brings with it a spiritual aspect.
