Does this sound familiar? It's the middle of the day, you're at work, you've long since eaten lunch, and nothing out of the ordinary is happening. Then, all of a sudden, you hear a voice in your head singing "bah-da-ba-ba-bah, I'm lovin' it" over and over, and it won't go away. And now you're craving French fries. That's what a good jingle does; it gets in your head and won't leave.
A jingle is a radio or TV advertising slogan set to a (hopefully) memorable melody. Jingles are written explicitly about a product -- they can be original works designed to describe a product or service, or to help consumers remember information about a product. As long as the slogan is instantly catchy -- and hard to forget -- there's almost no limit to what advertisers can say in a jingle. It can be a slogan, a phone number, a radio or TV station's call letters, a business's name or even the benefits of a certain product. In this article, we'll take a look at this unique advertising technique to find out how commercial jingles worm their way into our psyches.
