Magnetic tape technique

This video is intended as a demonstration of an extended piano technique that I used in one of my orchestral pieces, Time Lapse www.rogerzare.c... and chamber pieces, Oneironaut's Journey • Oneironaut's Journey b... (about 4 and a half minutes in), and will use in future chamber and solo works. I want to thank David Smooke www.davidsmooke... for teaching me about this technique.
All that is required is a piece of magnetic tape (tape from an audio cassette seems to have the ideal properties). Tie the piece of tape to any string on the piano with a simple knot. Then pull the tape taut with one hand, though not tight enough to stretch the tape. Use a finger or multiple fingers on the other hand to rub the tape with a small amount of pressure to produce the sound. If the tape gets stretched out to a thread, the effect can still work, but the tape is at risk of breaking.
Later in this video is a demonstration of the effect on a string in the middle of the piano, showing a different effect and an unexpected half step inflection. At the end of this video is a demonstration where I tied both ends of a piece of tape to two strings, a fifth apart.
