<p>I'm planning on applying EA to Princeton, and I also want to submit the optional arts supplement for piano. My question is, how should I record it? I know my iPhone's record quality is OK, but not great...I could also buy a $50-$100 microphone and use it with my computer to record. Or, I could book a session at a recording studio for a couple hours. Which sounds the best/most acceptable? Or if any other possibilities you guys can think of. Thanks!</p>
