I'm no musical scholar, or even musician, but I'd venture to guess that there is no classical piece which attracts as much admiration and derision as Pachelbel's Canon. (Note: TFP autolinks the word c-a-n-o-n in this posting to a site where you can buy cameras with that brand name -- just ignore that.) The Canon (not technically a "canon" as played today, but that's a detail) was written before 1700 by a German Baroque composer named Johann Pachelbel. It was popularized in the 20th century, at least partly by the movie Ordinary People. It is often played during weddings and church services. Musicians, and people who consider themselves sophisticated about music, loathe the Canon. Here's one very expressive excerpt from a blog posting: From a musician's standpoint, the most annoying thing about the Canon is the intensely positive reaction it elicits from most audiences. Why should something this easy to play be greeted with such enthusiasm -- when much more difficult or creative pieces get nothing but a bored shrug? Item: any classical music radio station that puts the Canon on the air gets an immediate wave of calls from delighted listeners demanding to know the name of the piece. Item: at a huge student loan processing phone bank in North Carolina, the music-on-hold consisted of the Canon on endless repeat. No one ever complained -- indeed, about every tenth caller wants to know what that wonderful music is. In short, the Canon is catchy. It has just the right combination of notes, at just the right speed, to ignite some pleasure center in the human brain. If you haven't been taught to be scornful of it, you like it. Another interesting commentary, mentioned in the blog post quoted above, is Blues Travelers' song "Hook". The lyrics bemoan the way trite, catchy, insincere songs (with musical "hooks") get people's attention and make money, unlike more honest or artistically meaningful ones. But the song itself is set to the exact same chord progression as Pachelbel's Canon, and guess what? It's catchy, and it became the band's best known song.
