Returning student, vocal coach in training. What program?

Hi! I already have a BA, I’m in my mid 40s and I’ve sung off and on all my life. (Musical Theater, gospel choir, college a cappella). I’ve also had a a career as a life coach, stay at home mom and sales professional (advertising). I play a little guitar too.

I want a thorough study of music to perform popular styles: r&b, pop, rock, gospel etc. I also want to be a vocal coach. Kids/teens/adults. I’m not currently interested in musical theater or classical.
I’d like to be in a collegiate environment. Wondering if getting a whole other undergraduate degree makes sense. Able to travel for the right program. Thank you!

I should have posted this to Music Major forum instead of MT. MT folks, feel free to disregard.

At Shenandoah Conservatory we offer a Masters of Music in Contemporary Commercial Music Voice Pedagogy. The degree gives students functional knowledge about how the voice works in all styles and helps them hone in on what they do best. We have had students singing everything from classical to musical theatre, jazz, rock, gospel, and rap on their culminating recitals and we cover all of the above in the coursework as well. It is the only degree of its kind in the United States. ~ VT
