The first drawbar(from the left) is 16' and sounds the octave below middle
C.
The second drawbar is indeed 5&1/3 feet, and sounds G above middle C. The
fifth.
Drawbar no. 3 is 8' and sounds middle C.
No. 4 is the 8th or octive, and sounds C above middle C.
All this depends on if in fact a C note is being played.
After the octive the rest of the drawbars add from the 12th to the 26th
harmonics.
But, the question referenced to A440.
If A above middle C is 440 then A below middle C shoild be 220.(with the
third drawbar only)
This means that if A below middle C is played with the First drawbar only it
will be 110.
Therefore the second drawbar(alone) will sound E in the octave above the C
octave(the 8th).
16 half steps above middle C.
I have a chart somewhere that shows the cycles per second of each note, But
it's been years since I've looked at it.
I'm sorta guessing that the A above Middle C played with only the second
drawbar pulled will sound around 660 CPS.
