Snapshot of Snape

This is from an email I sent in discussion with a young friend named Joshua, discussion on the whole Snape thing. The incident it refers to is one of my favorites in HBP and the type of thing that makes me love Rowling's writing so much. She creates such an intricate character in Snape. From Email: Just as an aside, here is one of the most fascinating things to me, maybe in all of book 6 ... when Harry hits Malfoy with Sectum Sempra, and Snape heals him ... she writes that Snapes healing incantations were "almost like a song" (HBP 523). She doesn't use music much in the series (that I can remember) and when she does I think it indicates something really important, maybe not to the plot but at least to the meaning. The only other place I can think of off the top of my head is the Phoenix song. The Phoenix is a very powerful but very mysterious and mystical image in the book. I think she is trying to give a hint to something very deep and mystical going on in Snape.
