Frédéric Chopin: Nocturne No. 20 in c sharp minor, Op. Posth (Arr. Spencer Cha) [MIDI] 

I decided to arrange Chopin's nocturne in c sharp minor for orchestra.
Please excuse the non-realistic audio, as it is a midi-generated audio file. I also used the piano score as the orchestra score is difficult to read (given how small the staves are and how many staves there are).
