In 1498, half a millenium ago, Emperor Maximilian I moved his court and his court musicians from Innsbruck to Vienna. He gave specific instructions that there were to be six boys among his musicians. For want of a foundation charter, historians have settled on 1498 as the official foundation date of the Vienna Hofmusikkapelle and the Vienna Choir Boys. The choir sang exclusively for the court, at mass, at private concerts and on state occasions.
