A poster with the user name @SpartanDrew with a jazz singer daughter had a long thread in 2017-8 I believe. Her kid ended up at the New School, did Berklee summer program prior to the application year, and was also interested in Loyola New Orleans. I believe Denver was in the mix but not sure. My memory is foggy! People seem to love Lawrence.
Since you have perused a lot of threads, you have probably seen a lot of suggestions already. One random example from 6/21:
I’m so glad to find this site! I’m new and this is my first post. My daughter is a rising senior and determined to be a vocal performance major. She plays piano, sight-reads solfege, performs with two vocal groups–choral and contemporary, recently learned guitar and ukulele, and enjoys composing. My husband (went to NEC) would love to see her happy in a music school but prefers she steer away from the Conservatory route unless it’s a school like Oberlin, Carnegie, or Lawrence which also offer a liberal arts degree. So far Thornton, UCLA, Oberlin, U of M, Blair, Carnegie Mellon, Peabody, Northwestern, and Lawrence are considerations. She’s an introvert, loves the intimacy of smaller campuses but would be thrilled with a program like Thornton which has a smaller music school within a larger campus. She’s in love with the oldies/contemporary music, understands the importance of a classical foundation, but not as excited about Opera. Any schools that might be a good fit? Any I should add to the list? Are any of the above heavily focused on Opera (which we may want to remove from the list)? Would love your sage advice!
