Question regarding music supplements

<p>Hi All,</p>

<p>I've been playing the violin since third grade, and I was planning on submitting a recording with my application as a supplement. I was just wondering, do colleges expect that I use a professional recording studio for my CD? My high school auditorium has recording capabilities, and I was also wondering if I could just use that. Additionally, I was wondering if colleges expected piano accompaniment with the pieces that have an accompaniment part? I'm applying early decision to Columbia University, if that makes a difference. </p>

<p>Thanks,
Natalie</p>
