Gudrun's Passacaille

Gudrun's passacaillle ; a new piece of baroque organ music I composed today for my friend the organist Gudrun who has multi sclerosis disease and wants to give a concert next month. So this piece has been written easy and without a staff for pedal but should sound as a normal organ music with a pedal part. Here the pedal part is played with the left hand and AP function.
Please do not take care of surprising tempo variations due to my small computer capabilities. The Pdf score is given in Attachment
