In your video "do re mi", when you sing "do re mi" you're actually singing mi fa sol, or G# A B to be precise. Why is that?
because it is singing harmony with the bass/chord, which actually is doing do re mi. that's why it still feels like do re mi. it should convey the feeling of do re mi to everyone except for certain musicians who have been trained only well enough to identify the melody but not enough to understand the bigger picture
