<p>Definitely look at Oberlin, the NEC/Tufts program, Bard (ask pointed questions about their ensembles if playing in a full-sized symphony orchestra is important to you - at least a couple of years ago their largest ensemble was more like a chamber orchestra in size, it may be larger now), and the program available at CIM/Case Western. Possibly also Eastman/U Rochester, but I do not know how many they admit to a dual degree or dual major program, and what their graduation rate might be.</p>
<p>Rice is a very tough admit and some of the music teachers there do not want their students doing anything but music. I am not sure whether or not that describes the horn teacher(s) there. The NEC/Harvard program as well as the dual degree programs at Juilliard and Peabody admit very small numbers and even fewer complete those programs. The last time I looked at the music curriculum at Carnegie Mellon, it had almost no room for anything else so a double degree would be really hard there. Curtis allows you to take some classes at Penn, but I have never heard of anyone doing a dual degree through that program.</p>
<p>I am not familiar with the quality of the horn teachers, but you may want to give U Maryland and Boston U a look as well.</p>
