Johann Philipp Kirnberger, Ich bin ja Herr in deiner Macht
Interesting in the prelude on “Ich bin ja Herr in deiner Macht” is that the piece is written in A major and touches on f sharp minor and c sharp minor. Quite daring for the time. Perhaps the piece was meant as showcase (or testcase) for one of Kirnberger’s own tuning systems?
The recording was done on the sample set of the Holzey organ of St. Peter and Paul in Weissenau by Prospectum.
