Meet the all-important Brass Reed
It is the brass reed that makes the sound we hear when playing a pump organ.
Whether your pump organ has 61 reeds or 961, if they're not in good working order you're going to know it very
quickly. It's surprising how just a small speck of foreign matter will cause a reed not to function, or not to
Although a reed has two primary brass parts, it is the reed tongue that's the
critical part(as seen in the illustration at right). The reed tongue must be able to vibrate freely in
order to generate the correct sound.
The only point where a reed tongue makes contact with its brass casing that surrounds the reed tongue is at the
back where there are two small brass rivets that hold the tongue in place.
When the tongue is suspended on all three sides correctly, the distance between the brass casing and the reed
tongue is about the thickness of a human hair. You can now better understand just how important it is that reed
tongues be absolutely free of anything.
It's during the pump organ’s restoration process that these brass reeds are individually removed, cleaned and
checked for any damage to the reed, or the wooden reed cell that it sits in. And if either is damaged, they are
replaced or repaired.
In today's home environment, pump organs are no longer subject to open windows that allow just about anything
blowing in the wind to come in the home. We can only imagine
what it must have been like a hundred years ago with all the soot in the air from everyone burning coal and
wood for cooking and heating.
So we can easily see "clean reeds are good playing reeds."
