Jingle

A jingle is a short song or tune used in advertising and for other commercial uses. Jingles are a form of sound branding. A jingle contains one or more hooks and meanings that explicitly promote the product or service being advertised, usually through the use of one or more advertising slogans. Ad buyers use jingles in radio and television commercials; they can also be used in non-advertising contexts to establish or maintain a brand image.
