Hello. This week we're going to be looking again at harmony in a little bit more detail. So for instance, we'll be looking at things like chord inversions, cadences, some harmonic sequences, and a little bit about modulation or changing key. I'm very pleased to introduce this week John Kitchen, who is a Senior Lecture here in the music department at the University of Adam Brook. He's also the university and city of Edinborough organist and a specialist in 17th century French keyboard music.
