or a point about him...
chorale preludes are not the most interesting pieces on the whole and relatively speaking; you have a melody, you have figuration around it.
One reason I'm putting multiple versions of pieces Bach wrote for teaching purposes- a project he never finished, at that, a project to write a chorale setting for each week of the liturgical year - is -
in part because (maybe for that same reason... if you're going to have a certain number of pieces, make them as different from each other as possible) what does exist of the project shows what can be done with the chorale prelude (in the opinion of the note-writer to the recording I have of part of the set, and I agree)
and because up to a point, I think hearing good and different interpretations of even more minor Bach is both pleasant, and interesting, and thought-provoking, instead of just redundant.
To sleep with me :)
