When Colin Kaepernick, the former NFL football quarterback, took a knee (knelt) during The Star-Spangled Banner at the start of the games, he created quite the uproar. I have written that I felt his using his visibility to call attention to the injustices against African-Americans and other minorities was in the best tradition of nonviolent protest. He paid a heavy price for his actions: though he reached a settlement with the National Football League and is now a free agent, to date no team has been willing to sign him. Anna Celenza, Professor of Music at Georgetown University, discusses Kaepernick’s protest in her introduction to a One Day University lecture titled: “Four Musical Masterpieces That Changed America.” I found her talk, which I watched on video, so enlightening that I’d like to provide you with some highlights. I’ve also added a bit of research from other sources.
