“Taking time out to concentrate on the structure and application of the Cycle was both fascinating and enlightening. It provides an insight into the structure and logic of music which in turn makes a piece easier to read and to learn.” - Bonita
“A very clear and insightful explanation of the Circle of Fifths. I liked the way you developed the concept from first principles and with class interaction. I think this really makes it easier to understand and to retain the key (no pun intended!) ideas. There were several light-bulb moments for me and I have come away with confidence that I can look at the Circle, and derive it, without being daunted.” - Bill
