This is more or less true simply because of the fact that the composition faculty at all the Ivies are very graduate oriented. </p>
<p>With that said however, if one does not wish to enter a conservatory, they are certainly your best bet. fhimas88888888 seems to want to get a very good liberal arts education- the Ivies, for the most part, fulfull that function. Furthermore, at the Ivies, you study music as if it is another academic disapline such as philosophy or math rather than the more careeriest/professional style you would encounter at say a conservatory.
Furthermore, if there is one field of music where it is infinately easier to be an autodidact, it is in composition. </p>
<p>One should obviously also consider schools such as Northwestern, Rice, Oberlin etc. which are not stand-alone conservatories but schools within schools. These schools often have double-degree programs set up. However, I strongly recommend that you find out how they are set up; double-degree programs are not all created equal. Some are very well planned out and some will just give you headaches because no one knows what’s going on and no one can give you any answers. </p>
<p>With that said, there are certainly many great composers in the US that did their undergrad at an Ivy or LAC rather than a conservatory. You certainly wont be at a disadvantage.</p>
