These are honor bands I know existed last year. I will post more information as I receive it.
The BYU-Idaho honor band takes place annually in January. I do not have any more information as of yet but have reached out to their faculty.
The Weber state university honor band takes place annually. I do not have information yet but have reached out to their faculty.
Please remember, you do not need to plan on majoring in music to attend these events. It is an opportunity to go to the colleges you are considering attending and learn about the school, the faculty and student life. Music scholarships are frequently awarded to non-music majors. You can continue playing music in college without pursuing a music degree. If you are considering a music degree, these are an incredible opportunity to see if you like working with the professors.
