If you can name a short (<5 mins) piece of music more beautiful, moving but also all-encompassing than Bach's "Air on a G-String" please do so; I can't. Listen to this interpretation before deciding: https://www.youtube.com/watch?v=2cVSgEdT4KI . Love, loss, despair, grievance, new hope, closure - it's all in there in this single, short, compassionate-but-not-sentimental, solemn-but-not-sad, perfectly balanced, ethereal piece.
