Step-by-step explanation:
In the Middle East and North Africa, singers cultivate a vocal timbre that has a nasal, intense, and strained tone.
This unique vocal quality is characterized by a strong nasal resonance, which adds a distinct flavor to the sound. Singers in this region often employ vocal techniques that emphasize nasal placement and create a tight, focused sound.
Examples of this vocal style can be heard in various Middle Eastern and North African musical traditions, such as Arabic music and qawwali.
