The ideal jingle may act as an earworm, causing the brain to recall a familiar, repeated sound. I mentioned proper catchy jingles because there's a science to producing the perfect sound for a business. Customers may have a negative reaction to your brand if your jingle is noisy, unpleasant, or disruptive. Even the first few notes of a song or jingle might elicit memories, prompting listeners to start singing the song or jingle right away. Take, for example, McDonald's. Is it to your liking?
