Percussion

Some organs contain percussion stops played by electric or mechanical devices. Tubular chimes, similar to those in an orchestra, are the most common of these. The range of the chimes is usually twenty-one notes from A below middle C. They may be played from one of the manuals or possibly from the pedal. The Zimbelstern is a group of very high-pitched bells mounted on a wheel, producing a jingling sound like sleigh bells. It is activated by an on/off switch.
