Beyond perforations: Welte-Mignon piano roll text and illustrations
“So, it’s the original karaoke machine?”
A recent visitor on a tour to the Archive of Recorded Sound made this comment to me as I showed off the roll I was cataloging. On plain beige paper, at first it looked like a regular piano roll. A label at the beginning. Expression and performance data perforations appeared as I unrolled the roll. Then, at the side: words! You can imagine gathering around the piano to sing along with a group of friends at a party, just as Stanford undergrads may have done at the Stanford Student Union in 1915 or Encina Commons in 1926.
