The source for this publication is a handwritten copy by August Wilhelm Bach of 6 preludes and fugues composed by Ernst Friedrich Richter. One of them has an opus number, but the rest has not. I do not know whether that is because they have not been published before or because Bach simply did not notate the opus number. If somebody knows the opus number that belongs to this Prelude and Fugue, I’d like to hear it.
Both the prelude and fugue are well written. Bach did not notate any dynamic indications in his copy. I choose to play this one with full plenum.
