Putting middle school activity on common app?

I performed for the Philadelphia Boys Choir and Chorale for 4 years during middle school. We traveled over the world and performed at Carnegie Hall and other renown places. I would really like to put that on my activities because it shows my music background during my youth and how i play two instruments now. Could i put this in the activities section on Common App? Thank you!

Not sure I would recommend that.

Is there a way you can work it in for the CA essay?

I could somehow, but it would be very hard. I just have two schools for regular and they are really competitive and I would really like to emphasize my music and athletics into my essay.

What sort of middle school did you attend that runs for 4 years? I know of 6-8, and 7-9.

So if music will be a piece of your essay, then it should be easy to work in the fact that you were in the Philadelphia Boys choir as a child.

Yes, indicate that you are committed to whatever your activity was at the middle school level, and that it is something you began ----- and have remained committed and invested in.
