By 1773 the Mozart family had outgrown their house on the bustling Getreidegasse and moved across the river to the more spacious ‘Tanzmeisterhaus’, the former home of the court dancing instructor. Wolfgang lived here until 1781, when he moved to Vienna. His father Leopold remained until his death in 1787.
More than half the building was bombed during World War II, but was restored and opened as a museum in 1996. Inside the house are documents, portraits and instruments that detail what life was like for the Mozart family during this period.
The Wohnhaus and Mozart's Geburtshaus are worth checking out, particularly if you've purchased a Salzburg Card that provides entrance to both. This one, however, is usually less crowded.
