Der Hölle Rache kocht in meinem Herzen, the second aria by the Queen of the Night in Mozart's opera Die Zauberflöte (The Magic Flute) is one of the most difficult arias to perform, ranging over two octaves from F4 to the almost supernatural F6.
It is difficult enough for most sopranos. I was blown away to see it performed by a treble (boy soprano).

Though not perfect and one would not expect so from a 13 year old boy, reaching the high Fs was incredible.
