Vienna

 is the capital city of Austria and the home to many notable artists, including renowned musicians such as Wolfgang Amadeus Mozart and Ludwig van Beethoven. According to Mario's Time Machine, in 1791, Mozart was about to begin his next opera, and only needed something to inspire him. However, the item that was supposed to inspire him, the Flute, was stolen by Bowser, and Mario later takes back the Flute and travels back in time himself to return it. Without knowing that the Flute needs to be brought to Mozart, he questions several people within Vienna, including Constanze Mozart, Joseph Haydn, and an unnamed opera singer. He eventually deduces the Flute's rightful owner, brings it to Mozart, and promptly travels back to the present after Mozart thanks him.

In 1824, Beethoven had completed Symphony No. 9, and was preparing to premier the composition at a Viennese theater. However, Bowser travels back in time and steals it from Vienna, and Mario later travels back in time again to return it. Mario, not knowing that the music sheet in his possession is Beethoven's Symphony No. 9, questions the locals in Vienna about the item and his whereabouts, including the owner of the Swan Inn, which eventually leds him to discover the sheet's true owner. Mario runs to Symphony Hall, where Beethoven is about to perform his symphony, gives him the music, and promptly leaves Vienna.
