This YouTube video is the first full documentation of Bela Bartok's
Welte piano roll recordings made at the Welte office in New York on
December 23, 1927.  The date of the recording is authenticated in the
book, "Apám" (My father), by Bela Bartok's son, Bela Bartok Jr., with
whom I participated as a performing pianist in a series of lectures
on his father at the beginning of the 1970s in the USA.

At the end of the video, a few Edison cylinder recordings by Bela
Bartok provide a direct connection with his field trips among peasants
of various nationalities (you will hear some authentic Rumanian folk
music recordings made by Bela Bartok at the beginning of the 20th
century).  The just uploaded video may be found at the following

The present owner of the original Welte rolls is unknown.  This
documentation may help in tracing the whereabouts of the original
rolls.

Given the existence of transfer technologies similar to those developed
by Wayne Stahnke (see his "A Window in Time: Rachmaninoff Performs
..."), it is crucial to locate the original rolls in order to preserve
their audio material in a technologically updated rendition.

The rolls bear these numbers:

  Welte Roll 7768
  Welte Roll 7791
  Welte Roll 7785
  Welte Roll 7767
