The apartment on the third floor
Mozart's Childhood Violin & the Rooms He Was Born In
The Mozarts lived at Getreidegasse 9 from 1747 to 1773, and the house still holds instruments Wolfgang played — what you're really looking at, floor by floor.

The power of Getreidegasse 9 is that nothing about it is symbolic. Wolfgang Amadeus Mozart was born here on 27 January 1756, on the third floor of what was then the Hagenauer Haus, named for the merchant family who owned it and rented the apartment to the Mozarts from 1747 until 1773. His father Leopold was a court musician and celebrated teacher; his older sister Maria Anna — Nannerl — was a keyboard prodigy in her own right; and the household the visitor walks through was a working musical enterprise long before Wolfgang made it immortal. The house has been open to the public as a museum since 1880 and is today run by the International Mozarteum Foundation, which keeps the emphasis firmly on authentic objects over theme-park recreation.
Instruments that were actually his
The museum's headline holdings are instruments with a direct, documented line to Mozart himself: his childhood violin, his concert violin, the so-called Costa violin, his viola, his fortepiano and his clavichord. This is what separates the Birthplace from every Mozart-themed attraction elsewhere — these are not period instruments 'of the type he would have played' but the physical objects on which a specific pair of small hands learned, practised and composed. The display pairs each instrument with audio examples of Mozart's works performed on that original instrument, so you can hear exactly how thin, intimate and human the clavichord sounds compared with the concert-hall Mozart most of us carry in our heads.
The clavichord and Constanze's certificate
The most quietly moving object in the house is the clavichord, which carries a certificate written in the hand of Constanze Mozart, his widow, attesting to its history — tradition ties it to the composition of The Magic Flute in the last year of his life. A clavichord is a private instrument, barely louder than speech, designed for practice and composition rather than performance, and standing in front of this one collapses the distance between the myth and the working musician. Constanze's note is also a reminder that the Mozart legend was curated from the very beginning by the people who loved him — she spent decades managing his manuscripts, his biography and his relics, and this certificate is that stewardship made visible.
Letters, portraits and the paper trail
Around the instruments, the museum builds its story from original certificates, letters and memorabilia, together with portraits painted during Mozart's lifetime — a crucial qualifier, since most of the Mozart faces on chocolate boxes derive from posthumous, idealised images. The letters are the family's own voices: Leopold's meticulous, ambitious, sometimes exhausting correspondence and the family's records of tours that took the children across Europe. Reading even a translated fragment beside the rooms where those letters were written and received does something no biography can: it re-scales Mozart from marble genius to a child in a third-floor rental whose father was simultaneously his teacher, manager and publicist.
Walking through an eighteenth-century home
The exhibition spreads over three floors and includes both original rooms and a middle-class apartment reconstructed as authentically as possible, showing how a family of the Mozarts' station actually lived — how they cooked, slept, worked and entertained in a handful of rooms. The curatorial route moves through his upbringing, his musical development, his relationships with family and patrons, and his lifelong passion for opera. It is worth resisting the urge to rush to the famous objects: the reconstructed domestic spaces are the context that makes the violin and clavichord land, because they show the modest, crowded, workaday world from which the music improbably emerged.
The floor that changes every year
One floor of the house hosts rotating annual exhibitions, which means repeat visitors — and Salzburg gets many — rarely see exactly the same museum twice. These themed shows dig into single aspects of the Mozart world in more depth than the permanent displays can, and they are also where the Foundation's research arm surfaces for the public: the Mozarteum holds one of the world's great Mozart scholarly collections, and the exhibitions draw on it. Combined with the facade's 'Flying Notes' installation, the effect is of a museum that treats Mozart as a living research subject rather than a sealed relic — which is, fittingly, how the city itself treats him.
Why an hour here lands differently
The Foundation suggests about an hour for a visit, and that is honest — this is a dense but compact house museum, not a half-day complex. What you are buying with that hour is proximity: the actual floor, the actual instruments, the actual paper. It pairs naturally with the rest of Mozart's Salzburg — the Residence across the river for the later family years, the Old Town lanes and squares he grew up performing in, and an evening concert to hear the music in the city that shaped it. If you only have time for one Mozart site in Austria, this is the one with the strongest claim to the word 'birthplace' in every sense.
