Mac -> iPhone song transfer

Good day, fellow mindwashed followers of the Great and All-Powerful Apple!

My question is:

I have an iPhone running iOS 7 and a Mac running OS X 10.7. Both are on the same Apple ID. Is it possible to get just one song onto my iPhone from my Mac, rather than the entire library? (From my iTunes library, of course)

(I know this is idiotically simple, I apologize)

Thanks in advance
