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. **

Together, the improvising melody instrument and the accompanying rhythm group work together to create a dynamic and cohesive musical experience, with the melody instrument taking the lead and the rhythm group providing the underlying groove and support. **

In some cases, the whistling sound may also be a result of a structural abnormality in the airway, such as a deviated septum or enlarged tonsils. **
