>>c'  = one octave above middle c (on a keyboard) = 1 ft. pipe =  approx. 512 Hz
c  = middle c = 2 ft. pipe = 256 Hz
C  = the C below middle c = 4 ft. pipe = 128 Hz
CC = two octaves below middle c = 8 ft.pipe = 64 Hz
CCC = three octaves below middle c = 16 ft. pipe = 32 Hz
CCCC = four octaves below middle c = 32 ft. pipe = 16 Hz<<

Actually, in this system 1' C is normally given as c'', 2' C as c'.

This system is mostly used by English and American builders, and is less
used than it used to be.  The more international system is the same (as I
give it) from 2' C (middle C) on up, and below is:

c0 = 4' C (Viola C)
C = 8' C (Cello C)
CC = 16' C
CCC = 32' C.

Subject: Straight vs curved saxophones

I just remembered another supposed characteristic of straight saxophones vs
curved ones.  Their response is said to be easier and prompter.  This is,
again, in addition to their having a brighter, reedier tone.

Subject: eyeball quiver

The resonant frequency of the average eyeball is approximately 12 hertz. However, you
don't have to play a note that low to get dancing digital displays. On my bass sax low
C# down to low Bb make my led clock display wierd. I believe what's happening is that
your head vibrates, but your eyetracking mechanism can't keep up with the
amplitude/frequency. Hence, your eyeballs are not resonanting, but are vibrating around
faster/more than your brain can re-aim them.

For further experimentation: rather than setting up your cumbersome low-frequency
musical instrument, simply look at a low-persistance scanned display, and give it a
bronx cheer. As you change the frequency of your tongue flap, you will see different
effects. Computer displays undulate and crawl around, led displays show the individual
segments in varying order. Use a paper towel to remove saliva from device under test at
conclusion of investigation.

BTW: info on eyeball resonant frequency comes courtesy of a conversation I once had with
a researcher at Cadillac. I'm somewhat embarassed to admit that the only other one I can
remember is that the resonant frequency of the average human female breast is 8 hertz.

Perhaps what you have here is one of the lowest pipes in a fractional rank
that is used in a particular mixture stop, so that it plays only with the
BBB, though sounding GGG#

Hmm. Could you put a funnel on the foot and a shield around the lip to get
enough differential to sound it? Or use a reed pipe. And add a pallet and
key and you have invented the Air Horn. That ought to put the
eighteen-wheelers in their place....

Subject: Need music

Hi all. I was wondering if anyone out there has the sheet music for:

"Opening Oriental" by the Brown Brothers (I need all of the parts). I'd love to play this on a 1904 Conn Bass Sax that's on loan to me.

Piano part for "Sax-o-phun" by Rudy Wiedoeft (Would like to get parts for both Alto and C-Melody Sax. The sax part stays the same, but the piano parts are in different keys).

If anyone has these, I'd appreciate it if some photocopies could be made. Please E-mail me privately at Frank.D.Diaz@WDC.com.

Thanks

Frank
