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

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. **
