Jingles are short, catchy phrases or words that are used in advertising and marketing. They are often composed of a few words or lines of music that are repeated throughout the advertisement. Tunes is a five-letter word for a melody or song, while RHYMES is a six-letter word for a phrase or verse that has a similar sound when read aloud. Together, these two words can be used to describe jingles, which are often composed of both tunes and RHYMES.
