Then you don’t get to claim his music is bad, “for a whole array of problems that can be measured either by technical analysis,” if you lack the tools to analyize it technically.
If I were to do an harmonic analysis of Gather Us In, arguably the most overdone Haugen hymn out there, and Holy God, We Praise Thy Name, I suspect that the harmonic structures would be equally basic and uninteresting.
If I were to take a Psalm setting from Haugen, which have arguably bad or improper texts, and compared it to Holy God We Praise Thy Name, I would expect to find the Psalm setting to be very interesting and theoretically “forward” from an harmonic stand-point, whereas Holy God We Praise Thy Name would remain basic and uninteresting.
What would then determine “good” music? The harmonic analysis? What people like? What music theorists define as modern, appropriate, or in compliance with music theory rules (which Holy God We Praise Thy Name undoubtedly follows probably to a fault)? What people can sing?
