Advertising tunes, also known as jingles, are short musical compositions used in advertising campaigns to help promote a product or service. They are typically composed of catchy melodies and lyrics that are easy to remember. Jingles are often used in radio and television commercials, as well as in other forms of media such as online videos and podcasts. The use of jingles in advertising has been around since the early 20th century and continues to be an effective way to get a message across.
