"Free" is the hard part. I don't know if you'll find something on the internet that would do that for you. Sibelius.com has a demo version that you can play around with, and it will print out one page of something for you with the logo emblazened across it, but I doubt it would let you import it into word. Another possibility - ask somebody with Sibelius to do it for you (a four line melody would take but a few minutes if I know the tune). Then it can be sent as an attachment to wherever you want. You'd need Scorch 2 to read it and hear it. It's a free plug-in. Let me know if I can help anymore.
