<p>Rosin is a very personal choice and entirely a matter of taste. Fortunately, it does not cost all that much to buy a new one and try it out for a week or two. My daughter thought she liked Carlsson's until she tried Pops, and that's about as big of a change as you can make.</p>
<p>As pcanon said, Rice is very hard to get into. On double bass it is nearly as hard an admit as Curtis because they have two great teachers, a fairly small conservatory that only takes as many basses as they need for ensembles and a price tag that is $10K or so less per year that most other top music schools. You really need to be in the top handful of players nationwide to get accepted into one of the bass studios there. If you are going for acceptance into the conservatory there, you will want to have the best tape you can possibly produce. Make sure it meets all the requirements listed on their web site. </p>
<p>If you want to study another subject at Rice and take lessons from a grad student who is sure to be really good, that is another story. You don't need a tape at all if you are not applying to the conservatory. From what I have heard, double majoring is problematical there, but perhaps pcannon can give us a more informed report.</p>
<p>Unless things have changed in the past couple of years, I don't think you need to do a tape for CMU unless you are unable to do a live audition there. (And you should do a live audition at the school unless it is totally impossible.) In fact, Rice is the only school I know of that has a pre-audition taped round for double bass (very common for violins, cellos, flutes and singers, but not for double bass.)</p>
