Chime Design and Build
Easy options for making good decisions when building tubular-bell wind chimes from tubes, pipes, or rods.
Rods typically have a relative small diameter offering a smaller radiating surface producing a quieter chime, but on occasion the longer sustain time can offset the reduced loudness and sound quite acceptable. However, once the tank has been cut to your desired length it is easy work to determine the fundamental frequency using an analysis program like Audacity ®, a free, open source, cross-platform software for recording and editing sounds. The process involves accounting for all frequencies from the fundamental (whether present or missing) through the many overtones, by the use of math calculations, acoustic measurements, and the careful grinding of the chime to achieve the correct length for the desired note.
