I wouldn’t want to hear Bocelli or a Dramatic soprano sing chant. They wouldn’t be the right voices to do it and would just sound horrible. Also, although opera isn’t as popular as pop music, it certainly hasn’t lost listeners or new singers. It’s extremely more competitive today than it was 50 years ago and there are tons of opera companies in this country today, whereas 25 years ago, a young American singer would have to go to Germany in order to get his/her performing experience. Today they can stay in the states and still be able to have a career because of all the companies and Young Artists Programs offered to them.
Anyway, comparing opera and sacred music, especially chant and early music, isn’t the best comparison. Although they both fall under the classical genre, they are of a different style of singing. Opera is for entertainment purposes and because it is an art form can and does bring a certain level of spiritual joy, but not in the same way as music composed specifically for the sacred. Also, opera is sometimes looked at in the “classical” world as the meat and potatoes area of classical music. It’s drama overload, very earthy and much of it, especially during the Bel Canto era was composed for the masses - meaning the average Giuseppie, Joseph or Joe because Rossini, Verdi, Puccini and the like were the favored composers of the day for everyone. So, you really can’t liken chant to opera. They wrote those works to entertain not to bring spiritual ecstasy. Whereas the sacred works of other composers who also wrote operas are performed differently than if they were singing an opera. In those days as well, the common man enjoyed both, plus even their versions of popular/folk music. Opera is definitely not on the same level as chant or polyphony.
I’m not putting down opera because I am actually a young, opera singer and will be performing Mozart’s “Die Zauberflote” literally in four hours (BTW - a singspiel that was also composed poking fun at everyone and everything for the common man - it wasn’t first performed at the emperor’s theater but for the average man’s theater). I also used to sing chant and early music - and believe me - It is a TOTALLY DIFFERENT way of singing and a different outlook on the music in general especially when you learn the history behind it and how western music developed due in part to the use of chant and then later on to polyphony, etc. Since I am a musician I do receive spiritual fulfillment whenever I sing or hear someone perform whether sacred or secular, but still in opera I’m there to entertain. For sacred music that’s not the case. Perhaps there to inspire, but not to entertain.
I’m not saying that every mass should have an overdose of only gregorian chant, especially since throughout the centuries there have been further developments in music to create even more spiritual inspiring and beautiful music. And yes, chant can be boring is not done correctly or if I’m not in the right state of spiritual mind. When my mind is quiet that’s when I get the most out of it.
I also believe that the pope is a little more intelligent than to just believe that chant is “superior” because it’s considered “classical”. In some way, chant really isn’t in the classical genre either - it’s in a realm of it’s own - even different from polyphony. Quite honestly, I never actually placed chant in the classical realm. The Pope is a trained musician and knows his music/church history and theory to have a deeper reason than to think it’s good because it’s classical. That outlook is for those who don’t know much about any genre of music in general.
At the Cathedral where I work at as a musician, we do two Latin NO masses a month there where chant, polyphony and motets from various centuries in Latin is employed. The majority of people who attend the Cathedral are visitors from around the country and the world. Although most do not have music programs like ours, many times do they approach the music director, priest or musician thanking them for the music and how spiritual and uplifting it was. Granted, perhaps they wouldn’t want that at every mass they attend, but it’s not like they were “bored” by it or totally turned off. If the musicianship is good and there is sincerity in the prayer of performing, it will inspire people.
