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

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. **

Patience and a steady hand are key to successfully untangling knotted chains without causing any damage. **
