What does it mean if you were invited by carnegie hall to come and preform? I was in school and this happened

Well, that should be a great honor It means you are being considered.

I just sang there too, over the weekend. I am in the Philadelphia boys choir and chorale. It was great. Congratulations to you and your school.

... Were you really? Or are you asking silly questions?

It means you are good enough to perform and it's an honor.

I suppose it means you get to perform in Carnegie Hall.
