Snape's Songlike Chant (Snape's Song: revised)

I was thinking about the part in HBP where Snape "...muttered an
incantation that sounded almost like a song.(HBP US version, pg. 523)"
after the Sectumsempra that Harry performed. This reminded me a lot of
Fawkes and his song, as well as his tears. Does anyone think there is
a connection between Fawkes and Snape? I just felt like this songlike
incantation was not a conventional wizard healing method, otherwise
we'd find Madame Pomfrey singing incantations as well as healing. I
haven't noticed that any other spell, incantation, etc. was ever
described as song-like, so it made me feel there was more to it,
considering the many posts about Snape's patronus being a phoenix and
so on. 
Just a thought.

add more support to my point. :)
