For Blind Willie Johnson fans you'll already know "I heard the voice of Jesus say ... " as a text from his song repertoire
and you will also know that "Dark Was the Night" is an instrumental adaptation of the lining out hymn singing tradition. But in case you've never heard what that singing tradition among African American churches actually sounds like, well, then you need to listen to this.
Wade in the Water, Vol. 2: African-American Congregational Singing
℗ 1995 Smithsonian Folkways Recordings
You can hear the song leader/deacon "deaconing" the words for the well-known lyrics before each wave of responsorial heterophony. Dargan put it well saying that it's neither a prescribed harmonic pattern nor a simple unison melody. It most certainly sounds nothing at all like the tune Blind Willie Johnson famously recorded and Dargan explained that there's a propensity to "flatten out" melodic contours along a series of revolving and recycling melodic tropes which you can vividly hear in this remarkable performance.
Because it's an old lo-fi recording you might not hear the foot stomping and hand clapping rhythms at first but that's another element that you can hear in this tradition where a completely non-measured set of congregational phrases emerge and are progressively given firmer rhythmic accompaniment that has a tempo shift about half-way through.
I learned of this album from William T. Dargan's book
Lining Out the Word: Dr. Watts Hymn Singing in the Music of Black Americans
and if you want an even more radically different variation on a popular text from the African American Christian music traditions check out this recording by Doris Akers!
I'm still working through Dargan's book but I intend to blog about it once I'm done. Meanwhile, I can't resist sharing tracks from albums he recommended for listening. Fortunately the Wade in the Water series is Smithsonian Folkways which means it's not some wildly out-of-print thing you'd have to impoert or order from a university press you might not have heard of before like a couple of other albums Dargan recommends.
