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

Rhythm refers to the pattern of sounds and silences in music, creating a sense of movement and pulse. Melody is the sequence of musical notes that are perceived as a single entity, often the most recognizable and memorable part of a song.

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. **
