BWV 709 is a chorale prelude with a richly decorated cantus firmus. Like every true Dutchman I simply can't avoid the use of 8' 4' 3' + Tremolo for the cantus firmus.
BWV 726 is a chorale with quasi-improvisational scales between the hymn lines. Theories about how to play this short interludes differ. Do you play them exactly in time or should you play them in a free manner. I clearly went for the ad libitum option.
Channel settings:
Front 65
Rear 90
Warning: the second piece is much louder than the first piece, so don't be shocked and let your ears survive!
