They are doing the Kyrie from Vierne’s Messe Solennelle at a local church. The problem is that I know the organ at the church was built to be tuned to Werkmeister III. The piece is in c# minor and is for 2 organs. The second part is going to be played on a keyboard (it mostly just doubles the choir). That instrument will most likely be in Equal Temperament and most likely will not be adjustable to Werkmeister III.   My request is for any of you out there that have experience with Werkmeister III to let me know if you think that we are headed for a major train wreck at dress rehearsal Friday with these two temperaments on the two instruments playing in the key of c# minor. I can transpose to c minor or d minor if they would work better.   Any help as to how to avoid disaster would be appreciated.   Thank you.   Rex Roseman   </div> </body> </html>
