@browniemom - please review again the Double Degree Dilemma. There is an enormous difference between a Double Major and a Double Degree. If he’s at a program without a School of Music which does not offer a BM - such as Columbia - he would be pursuing a double major - two BA’s. Anywhere with a School of Music or Conservatory attached, or in conjunction (like Tufts/NEC) will be a five year Double Degree program. I’ve never heard Carnegie Mellon referenced on here for jazz, so no idea about that one. As @dramasopranomom said above, the lists from @StacJip and @ScreenName48105 are the place to start!
