How does melody typically function in popular music?

In popular music, melody often functions as a primary focal point that engages listeners. A catchy and repetitive melody has the ability to grab attention and make a song memorable. This quality is integral to the appeal of many pop songs, allowing them to connect with a wide audience. Repetition in melody can create an earworm effect, where the melody lingers in the listener's mind long after hearing it. Such characteristics help to establish an emotional response and enhance the overall enjoyment and accessibility of the music.

While complex melodies do exist in certain genres, they are less common in mainstream pop music, which prioritizes simplicity and memorability to encourage sing-alongs and repeated listening. Therefore, the function of melody in this context is not merely decorative but central to the song's structure and appeal.
