Piano wars

To compete with other piano builders, the Erard firm had a potential advantage in having workshops in two different countries. The success of the double-escapement action convinced the Erards to begin making pianos at their London branch. To maintain their position of dominance, the Erards relied increasingly on virtuoso pianists who would promote their instruments in concert. These artistic sponsorships were facilitated through performances at the salons Erard (later the Salle Erard) on the rue du Mail, which became one of the most important concert venues in Paris.
