Deletion of How Sacred Harp music is sung

Comment: The article Sacred Harp discusses the book and its historic context while this article discusses singing techniques so I don't see any good case for just deleting this.  It probably needs a better title, like Characteristics of Sacred Harp Singing.  It's not a technical guide and  does not apply as it's a description of a practice not a manual for doing it.  I share concerns about sourcing and possible OR so there is certainly a need to improve this but I don't agree that we're in deletion territory at all
