Dunno if I should ask here, but I don't know the other obscure corners of GS. I spend my time here only.
Got a question from my daughter, who helped the organ player with the registration during last weeks performance.
The choir was on the floor in the church, under the organ (Well, a bit more forward of course).
Easily 10 to 15 meters from the heart of the choir to the organ's console.
Now, she asked my why they heard the choir:
1) 1/2 to 3/4 of a second later (I can explain a bit... but half a second is 150m, not 15...)
2) About half a semitone lower (!!)
Any thoughts about how this could happen (If it really happened) ?
