there is NOTHING wrong with doing chorus all 4 years! He has found something that gives him joy!
WHY on earth would you even CONSIDER making him cut back on that?
My DS’s ONLY elective classes in HS were music related, and he did just fine when it came to college admissions.
Colleges DONT want JUST “well rounded” students. They also want “pointy” students- those who demonstrate intense interest in one area.
relax mom!! Let your DS enjoy school…
