GLASS-ON-TINE

Here we have glass tubes loosely attached to the ends of kalimba tines, played by stroking the glass with moistened fingers. The result is a mixture of roughly pitched moaning and an edgy rattle of loose glass against steel. To stabilize the positioning, there are narrow machine screws extending through the ends of the tines and up into the lower ends of the glass tubes. 

In the sound clip, Glass-on-Tine is joined by several percussion instruments and a chorus of slide membrane reeds.
