First, find the characters from character map.

There are two notes in there, so just copy/paste them out.

Then use the /sup and /sub tags (within the pointy brackets of course) to make them dance. Quick tip, rather than making them dance upwards with sup, then down with sub, close all the sup tags to bring the notes back down to the baseline, then use sub to go below the baseline. If you don't close your tags to bring them back up/down you'll just get smaller and smaller and smaller.
