Bach Inverted is a composition study in which the Well Tempered Preludes and Fugues of J.S.Bach – the “Forty-Eight” – have been re-imagined in their opposite (or inverted) mode.
Bach’s concept was to write a prelude and fugue in each of the 12 major and 12 minor keys. And so, from the 24 individual keys was produced 48 distinct works. These were completed in 1722.
Twenty years later, Bach repeated the process with Volume II. So now there are 96 exquisite works.
Bach Inverted takes each of the 96 works and re-arranges them in their opposite mode. That which was major is now minor, and vice versa. Strict rules were enforced, notably that all note names be respected while permitting alterations (flat, sharp, double flat, double sharp, natural). No notes were omitted nor added.
