Also keep this in mind: at the recent NPM convention attended by 3,000 plus Catholic musicians, the opening speaker invited everyone to join him in the most common non-strophic hymn in the Catholic world: Ave Maria. Only about 1/4 of the people in attendance could join in. This is pure speculation but I would suggest that this represents progress over 10 years ago, a time before the Parish Book of Chant and the many youtubes and digital resources that have been evangelizing for the chant. What this means is that among Catholic musicians who care enough to attend an event on the subject, only 1 in 4 know the most basic chant popular in existence, one that uses a core text of the faith.
This is represents not only a loss of a sacred tradition but a loss of Catholic musical identity. This is where we are today. The good news: there’s nowhere to go but up.
