Tubular Chimes, Altered
These are tubular chimes modified in various ways to alter their vibrating patterns and resulting tone qualities in unusual ways. Included are tremolo chimes, dual-tone and chordal chimes, chimes whose sounds are enriched by their own internal air resonance, and chimes whose sounds are distinctive because their overtone recipes have been modified in different ways. You can see and hear more of these chimes in the video linked below, and you can read about them in much more detail in this posting.
