app questions

<p>just had two questions I hope I can get answered
1. Is it true that if you are not planning to major in music, you should not bother sending in a recording of music? If you do send one, does it have to be a high quality recording?
2. When schools on the common app ask for teacher recommendations would it be better to mail them in an envelope with a letterhead? What kind of envelope should it be in?</p>

<p>Thanks for all the help!</p>

<li><p>no, if you're talented, adcoms are interested in hearing you regardless of your major.</p></li>
<li><p>envelope probably doesn't matter at all.</p></li>
