There are a lot of strange musical instruments out there. The didjeridu is a giant pipe that plays a barely-audible bass tone. The organ has hundreds of little nobs, keys, pedals, and switches to create several different sounds. The theremin plays eerie music without anyone even touching it.
But I have never seen anyone play a saw:
You heard me right. A saw creates a slight tone when a violin bow is rubbed on the smooth edge. By bending the saw, you create different tones.
If you live in the New York area and have been on the subways, you may have seen this woman perform. Her name is Natalia Paruz, the “Saw Lady”, and she has perpetuated playing the saw as an art form. She has performed with the Israel Philharmonic Orchestra, the Westchester Philharmonic Orchestra, and the Royal Air Moroccan Symphony Orchestra. She has performed all over the world, including in the New York subways.
