As I posted yesterday, I have an order for a wooden pipe Caliola, and
have been unable to find any pertinent information. I know the compass
is said to be F below middle C to 44 notes above to C, but what are the
actual frequencies (in Hz, please)?
Are the pipes stopped or open? Doyle Lane's book of Wurlitzer scales
shows the longest pipe as being 37-5/16 inches. Also the widths and
depths appear to be the same, i.e., square. I'll be most grateful for
any definite information on this elusive instrument.

[ The 44 pipes span from F below Middle C up to high C. Using MIDI
[ note numbers this is 53F up to 96C. Wurlitzer calls them "flutes",
[ they are actually open flutes; the tone is less strident than
[ Wurlitzer violin pipes. These measurements were observed at the
[ Caliola owned by Bob Fine (destroyed by fire in October 2003):

[ Note depth width (inches)

[ 60C ? ? Middle C (no data)
[ 66F# 1.695 1.695
[ 72C 1.40 1.41
[ 78F# 1.15 1.667
[ 84C2 0.968 0.970
[ 90F# 0.825 0.830
[ 93A 0.770 0.770
[ 94A# 0.756 0.780
[ 95B 0.735 0.745
[ 96C 0.715 0.727

[ Note 60C (Middle C) is 261.63 Hz for A=440 Hz. The organ normally
[ is tuned equal temperament. -- Robbie
