A jingle is a short, catchy tune or song used in advertising to promote a product or brand. These musical phrases are designed to be memorable, making it easier for consumers to recall the product when they hear the jingle. Jingles often include simple lyrics that highlight the benefits or features of the product, making them effective marketing tools. Jingles can be found in various media, including television commercials, radio ads, and online promotions. Famous examples include the McDonald's "I'm Lovin' It" and the Kit Kat "Give Me a Break" jingles. Their repetitive and melodic nature helps create a strong association between the jingle and the brand.
