<p>Do students ever do that? Because I have a very short time playing guitar, 2 years, but I think showing what I play through a music CD is a lot better than just mentioning that I play guitar. Especially because hundreds of applicants play guitar, and a bunch of them have had formal training for more than 8 years or so. I've never had formal training, unless you count copying what guitar players do on youtube formal training.</p>
