The circle of fifths is a visual representation of the 12 tones of the chromatic scale. It dates back over 300 years, but is still widely utilized by musicians. With this circle of fifths pendant, you have music theory in an endless ring of melody and harmony.
The image is printed on a translucent medium in order to give it a slightly luminescent look. The back of the 1" glass pendant is sealed with a jewelry-grade resin and is water resistant (although you should still not wear it swimming or in the shower). The bail is silver-plated and on your choice of a black cotton cord with a silver clasp, or a silver chain.
