Hear the Piano Rolls

Ignace Paderewski at the Welte-Mignon Studio

The Stanford University Piano Roll Archive provides digital access to the piano roll collections of the Archive of Recorded Sound and is comprised of digital scans in the form of full-color and monochrome image files, MIDI files, and audio files. The image files are derived from a master TIFF file intended to permanently preserve the musical data encoded exactly as they appear on the original paper roll. The musical files derived from the master file represent possible interpretations of the data that closely resemble the experience of hearing the rolls played on a player piano. This site allows the user to search, browse, and explore the wide range of piano rolls in the Stanford Archive and to learn about the research conducted at Stanford on player pianos, rolls, and their significance to performance practice.
