Can I play a song of different language with piano?

Yes, well, we all have our areas of expertise don't we? Mine is music only, 40 years, studying, playing, teaching, composing. I'm a total beginner as far as almost all other subjects are concerned, but I'm always open to learn from others. When I am corrected by others because I am clearly wrong....I thank them sincerely.
I suspect that you've learned a thing or two about the basics of music theory from having contact with me, instead of acknowledging this in a positive way, you hit back with a childish putdown of sorts.
Am I really a rude intellectual snob?
I'm sorry you feel that way.

I didn't even make it to high school pal, it would be ridiculous of me to pose as an intellectual. However, I am very good at what I do. Teachers answer questions as clearly as they can, this itself is a challenge. Sometimes music teachers learn more than the students do.
It's a humility game, if you were a student of mine, we would have a problem.
I would give you your $ back and ask you to please leave.
I'm sorry if I intimidated you, but that is clearly you and you alone.

If you must continue thinking that you are qualified to answer ANY questions having ANYTHING to do with music no one can stop you with this fantasy of yours.....but don't expect any one to take you seriously, or enable your delusions, or show you respect. You don't deserve any.

Stick to what you know? got it punk? good.
