"O, wie will ich triumphieren" (or, "Ha, wie will ich triumphieren"), is an aria for low bass from Mozart's "singspiel" "Die Entführung aus dem Serail".

 It features rapid precision-coloratura, abrupt octave-leaps between the upper and lower registers, and extended low notes, including a drawn-out low D (D, one of the lowest notes demanded of any voice in opera).
 Mozart wrote it with one particular bass in mind: the very famous Ludwig Fischer.
