Having thought about the possibility for many years, this one was actually my first try-out in re-tuning the organ.
My plan is to develop this music further under the title "The Slow Tune", in different versions on various organs. Of course I tune the instrument back again to its original tuning after the concert.
This performance was the closing concert of festival Vestafor, the first of its kind, in beautiful Rosendal, Hardanger, Norway. Huge thanks to Christian Meaas Svendsen for the invitation to this wonderful festival.
