Sometime around 1750, Stein relocated to Augsburg, where he served as organist and also built keyboards, including many experimental instruments such as an enormous harpsichord with four choirs of strings and a vis-à-vis instrument that housed both a harpsichord and a piano. Some scholars have suggested that Stein may have apprenticed in the Silbermann shop learning to build pianos, although there is no documented evidence of this. Early in his career, he may have become familiar with the pianos of Johann Andreas Silbermann (1712–1783), the nephew of the great Saxon organ builder and piano maker Gottfried Silbermann (1683–1753), who worked in nearby Strasbourg. Stein was born in Heidelsheim, Germany, a small town on the Rhine. The basic form of the Viennese piano was invented in Augsburg by the organist and keyboard maker Johann Andreas Stein (1728–1792). Through the enormous influence of Vienna, which was then the center of the musical world, these pianos would become known throughout Europe and used by most of the great composers of the classical music period. Like its counterpart, the English piano, the so-called Viennese piano began as a regional tradition and was first built by makers and players mostly in Austria and southern Germany. The Viennese school of piano making produced one of the two distinct types of piano to develop in the eighteenth century.
