Just finished adding numerous entries on the Moravian use of trombones from Stewart Carter’s excellent “Trombone Ensembles of the Moravian Brethren in America” (in Brass Scholarship in Review, 1999). The entries can be found in the 18th century, 19th century (1st half), 19th century (2nd half), and 20th century. I always enjoy Stewart Carter’s writing: meticulously detailed research, extensive documentation, no self-aggrandizing, no personal ax to grind. Great, reliable stuff.
