What is a nose in singing?

In singing, the term "nose" often refers to the nasal resonance that can affect the tonal quality of a singer's voice. When a singer projects sound through the nasal passages, it can add brightness and warmth to their tone. However, excessive nasal resonance can lead to a "nasal" sound, which is generally considered undesirable. Singers often strive for a balanced approach, utilizing nasal resonance appropriately to enhance their vocal performance.
