Music Double Majoring and Supplement Applications

<p>I've applied to some UC's (I, SD, R, LA) with Computer Science as my first choice and music (music composition for LA) as my second. My plan is to double major in CS and music but to take them one at a time, so finish my CS degree and then start up music. Music requires a supplemental application and audition. For all the schools except LA I would have to perform some pieces in an audition. For LA I have to submit a portfolio of originally composed pieces and then go to an interview where I have to show I have some keyboard (piano) competence. At the moment I don't think I'm skilled enough for the auditions and I don't know how to play the piano (yet).</p>

<p>So I have two questions:</p>

<ol>
<li><p>If I don't turn in the supp app and I don't schedule an audition, will that automatically get me denied for the school completely even though music was my second choice, or would they still consider me for acceptance just only then consider me for CS. If they would deny me for not turning in the necessary forms and audition even though its my alternate major, can I call them and tell them I don't want music as my alternate major to avoid this?</p></li>
<li><p>Is it possible to apply for music as a second major after already attending the school? So assume I did get in for CS and after being there for a while (let's say two years), could I apply for music as a second major when my skills are better? If so, would the process be the same as the one I described above? And disregarding skill, would it be harder to do this? Like pretend there is person A and person B, and they have the same level of musical talent and skill but person A is applying for the music program out of high school and person B is applying to declare it a second major after attending the school already for 2 years. Would it be harder for person B to get into the program than person A?</p></li>
</ol>

<p>The supp apps are due in a few weeks so I would truly appreciate some replies asap.</p>

<p>Thanks in advance.</p>
