Now Waterhouse is going to demonstrate that Bach can sound good even played on Mr. Drkh’s organ, if you choose the right key. Just as Father John and Mr. Drkh are about halfway up the aisle, Waterhouse slams into that old chestnut, Toccata and Fugue in D Minor, except that he’s transposing it into C-sharp minor as he goes along, because (according to a very elegant calculation that just came into his head as he was running up the aisle of the church) it ought to sound good that way when played in Mr. Drkh’s mangled tuning system.
