Bach was so mathematical and I liked this idea that you could have one instrument going, 'One, two, three, four', and then you have another instrument going, [double time] 'One, two, three four', and another instrument going, [doubled again] 'One, two, three, four, one, two, three, four', so you could add twos and fours and eighths, and that happens a lot in Bach.
