Supplementary Materials question?

<p>Hi Everyone!!
Just a quick question as I’m doing some last minute updating…
but I’m submitting some music files as supplementary material and I was wondering how people suggested I do some description?
The upload website for Yale’s supplementary materials says to just do “Piano Sonata No. 2 in B flat minor. Op. 35, Scherzo. Frederic Chopin.” for example, but should I include my own personal description and write-up? Include why I chose those pieces? It would not be any extra work for me since I already wrote those out, but should I cut down on some letters to fit the 500 characters and include that?
Thanks and good luck to all!!</p>
