What is the difference between pop singing and ethnic American singing?

American voice is not leaning back, brother upstairs, you answered wrongly! Leaning back was the most common way of vocalizing in the 90s! Nowadays, the way of vocalization has been corrected, and it is all about leaning the voice forward! Of course I believe the owner should have yawned! That airflow is what passes through the chest cavity and reaches a ****ing sound with the head cavity! Of course the breath must sink, the lower it sinks, the more beautiful the singing voice! Singing high notes will be easier! I hope my answer, the owner can adopt!
