<p>I don’t know if what I know helps across the board, since pre-screening CD’s and how they are handled probably varies according to the school. However, I think you need to keep things in mind:</p>
<p>1)From what I have heard from people who have gone through the admissions process, and hearing presentations by admissions people, a perfect screen cd might actually work against a student. With recording technology, it is possible to put together using editing multiple takes a ‘perfect’ screening, you could use programs that for example correct intonation errors, any number of things (this could be done with a home pc and a decent recording program)…but I suspect that would raise red flags, because no performance is ever perfect (you being a violist, there is a funny example from the old Star Trek, Next generation series, where Data the Android figures out a character playing viola with him in chamber music is an android, because “you played that piece exactly the same way when we performed it as you did in practice, only an android could do that” <em>smile</em>)</p>
<p>I think it is better to do your best and submit it, as others have said some of what they are looking for could be the ability to recover. </p>
<p>2)Prescreening from what I am led to believe is not there to screen the way they do on live auditions, the idea is to cut it down to people with a reasonable chance, even at the most top level conservatories. If what I know is correct then it is really to fish out those that have no chance, those not worth auditioning. I know there is this impression that those screening this are looking for any chance to get rid of people from the process, but I have to say that goes against what I have experienced so far (as limited as that is), if anything, most of the screeners have a hard time weeding people out, it isn’t a joy. </p>
<p>3)Also know that the people screening for the most part have probably been doing this a long time, and they know that a)errors can happen and b)that that doesn’t necessarily mean the person is bad. They have had bad auditions, and what they are probably listening to is the overall picture, rather then looking for mistakes to weed them out. If the overall performance is good, if the intonation is solid, there is musicality in the playing, following the score in terms of dynamics and tempo,etc, then probably the screening CD will be fine, in terms of what they are looking for.</p>
<p>Again, this is just what I have seen so far and heard about, but hopefully it will help take away some of the angst (though I suspect not much)</p>
