"Once a piece of fabric became entangled in my drilling machine. Through the rapid
rotations the fabric generated both vibrations and interesting humming sounds. As
appropriate sound bodies for Wrummer, I found fabric foils used for truck tarpaulins.
If the foils are perforated, they vibrate stronger with various overlays/superimpositions.
The sound ranges from whooshing, to wrumming to almost drumming fluttering."
The mechanical principle: drilling machine motors allow circular truck foils to rotate fast.
