In the 21st century, it's easy to take technology for granted and forget that in the time of Johann Sebastian Bach (b. 1685, d. 1750), there were no cars, busses, airplanes, TVs, radios, movies, tape recorders, electric lights, or computers. People used candles to light their homes, and horses were the fastest way to get around. There were excellent plays and opinionated theater critics to review them, but no cameras to film the actors and actresses. Recording technology had yet to be invented, so the only way to hear classical musicians was to hear them performing live. Although the classical artists of Bach's time could not be recorded, they left behind their compositions, and today's classical musicians continue to keep them alive.
