Therefore, harmony belongs more to the realm of harmony itself. **

Melody is the sequence of musical notes that are perceived as a single entity, often the most recognizable and memorable part of a song. Harmony involves the combination of different musical notes played or sung simultaneously, creating a pleasing sound. While rhythm provides the framework for the timing of music, melody is the main tune, and harmony adds depth and richness to the overall sound. **
