How does singing from the diaphragm help improve the voice quality of a singer?

Singing from the diaphragm allows for better breath control and support, leading to a more powerful and resonant sound. This technique engages the core muscles, providing a stable foundation for vocal production and reducing strain on the vocal cords. As a result, singers can sustain notes longer, produce a fuller tone, and enhance their overall vocal quality. Additionally, diaphragmatic breathing helps maintain consistent airflow, which is essential for pitch accuracy and clarity.
