Ahah! now I see the problem. There's nothing wrong with 42 scale, but
42nd halving is almost unheard of.
There is a great difference between the scale of an organ and the rate of
halving. "Halving" refers to the rate at which a rank of pipes gets
narrower as you go up the rank. For example, 17th halving means that if CC
is x millimeters in diameter...once you get 17 notes up the rank, the
diameter will be x/2
The only example I could imagine of 42nd halving is in extremely old
organs. Ancient organs (we're talking medieval) were built with a constant
diameter throughout the whole rank...meaning that the bass sounds stringy
while the treble sounds fluty. Sorry, but I can't remember the source for
all this, anybody out there remember?
