This chime creates a soothing sound "illusion" as the precisely-tuned tubes work together to create a rich harmony and wonderful magic!
This illusion seems to create more tones than the number of its tubes (such as low bass notes created in your ear)! The result is as amazing as it is unique, since we use a beautiful ancient tuning not heard on any modern instrument. This is called the Natural Harmonic Overtone Series. It's magic to your ears.
