Professor Nicholas Baragwanath, author of the groundbreaking "Solfeggio Tradition" (published by Oxford University Press), returns to the show to talk about Hexachordal Italian Solfeggio. This was the method of solfege instruction that was employed at the famed 18th-century Neapolitan Conservatories, using 6-note overlapping hexachords, instead of the usual 7-note systems we use today. Professor Baragwanath answers popular questions and demonstrates solfeggio in numerous settings, from beginner lessons to more advanced examples.
