. Rats, could have done at least half a dozen Mazurkas in that time
I am glad about your decision.
And thank you too for your explanation regarding that choral structure. No easy food I think, but it is a clever approach to understand the upper long notes in the parts with 4 voices as cantus firmus on a separate manual, although it is not directly seen from the score (I have seen only an internet score).
Also thank you for showing how a Sesquialtera register sounds (was it alone, or some additional registers on the cantus firmus?). This register liked Bach that much that he requested to have it on every manual on his Arnstadt organ (but he did not get it). I think I need to couple a quint and terz register to hopefully come a bit close to that sound on "my" little organ
Ok, there was a slip, but also the trills could come better. I think if you would decice to spent some hours more on that (even for the danger that the next mazurkas come some days later), it would come out more fluent. I know that it is no easy playing, to take with left hand the notes from two different note lines (just don't know the english term), and the contrapunctus stuff with pedal is no easy food either. I admire how fast you get the notes together. Multiply the practising time you need by 10 or so, then this is what I need...
