Wikidata:WikiProject Piano Rolls

Aim and Scope

WikiProject Piano Rolls originated as part of the Stanford Piano Roll Program, a collaboration between Stanford Libraries and the Stanford University Department of Music to digitize, preserve and make available scans of player piano rolls held in Stanford Libraries’ collections.

Entity Model

The entity model is based on the WikiProject Music model for recorded music. The primary entities are related through the recording or performance of and tracklist properties.

Composition

Represents the musical work that is performed and recorded on a piano roll. For example, Chopin's Nocturne No. 8 in D-flat major, Op. 27, No. 2.

Label (English): the most common name that the work would be known by an English-language speaker. The 'English' label does not need to be an English title if the composition is well-known by a foreign-language title, e.g. "In der Fremde" by Schumann.

Description (English): A brief description to disambiguate the composition from other items with the same name. Prefer the format: [year] composition by [composer].
