1. I have given two lectures on Buxtehude in recent years, one at the 16th Biennial International Conference on Baroque Music, University of Music and Dramatic Arts Mozarteum, Salzburg, Austria ("Distinguishing Between Passacaglia and Ciaccona in the Ostinato Organ Works of Dieterich Buxtehude"), and the other at the 15th Biennial International Conference on Baroque Music, University of Southampton, England (“Rethinking Buxtehude as Harmonist”).
2. The lecture at the Mozarteum morphed into my article, “Buxtehude’s Passacaglia Principle,” published in the Rivista di Analisi e Teoria Musicale 20, nos. 1–2 (2014): 77–98. This is my second article on Buxtehude, the first being published in the Diapason (“Rhythm and Meter in Buxtehude's Toccata in D Minor BuxWV 155,” Diapason [July 1989]: 14–16).
