Some musicologists try to make a “splash” by saying that Bach was totally forgotten when he died—remembered only as an organ virtuoso—and that his sons were more famous than he was. Such an idea is indefensible. It is true that musical styles changed in 1750AD—but this is normal. Musical styles change constantly; e.g. much of the repertoire of Hofmann and Rachmaninov was considered “garbage” toward the end of their lives. But those who carefully study the lives of Wolfgang Amadeus Mozart, Christian Gottlob Neefe, Franz Liszt, John Field, Hans von Bülow, Felix Mendelssohn, Frédéric Chopin, and countless others realize that Bach was revered. It’s true that his music was seldom played in public, but music by “dead composers” was generally speaking not played in public until approximately the middle of the 19th century.
