Discovered today to my joy that there exists on YouTube a cornucopia of videos of my first harmony teacher, whose much-more-than-a-parlor-trick is to take suggestions as to themes and composers from the audience and to then improvise a setting of the first in the style of the second. Playing examples in class, he would often wander off a bit in various directions, and was quickly able to show how, say a Bach chorale would progress through historical harmonic developments.
