Key colour and diatonic scales are anthropomorphized as a peacock, hare, kingfisher, or cat, combining J.S. Bach’s landmark of musical pedagogy, Das Wohltemperierte Klavier (The Well-Tempered Clavier) with illustrations by 19th century French artist J.J. Grandville. This piece is from An Anthology of Familiar Tones, which questions what it means to be ‘in tune’.
