Yesterday’s post focused on the number 14. Today, being the Ides of March, I’m concentrating on the number 15.
Of course, Bach’s Two- and Three-Part Inventions come immediately to mind. Comprised of 15 inventions (in two contrapuntal parts) and 15 sinfonias (three contrapuntal parts), they were originally written as exercises for his students. The two groups of 15 pieces are neatly arranged in order of ascending key, each group covering the eight major and seven minor keys.
Hmmm…perhaps the inventions and sinfonias were exercises for Herr Bach, as well!
