What does this very short sample of music remind you of?

There is a very small sample of music that has been stuck in my head all week. I took the music and wrote it down in Finale, from which I produced this audio sample.

Although I don’t think that the music sample is from any particular piece of music, I think that the style of music sounds familiar.

So, what does this piece of music remind you of?
What style of music is it? I honestly have no clue.
Do you know of anything that sounds similar (maybe too similar)?
