This site collects the various projects that I have created as part of my dissertation Grünfelds Geist. All of them have Grünfeld's recording of Schumann's Träumerei for Welte-Mignon (1905) as their subject.

Data

Roll edition

The edition of WM 225 as JSON-LD in the Roll Edition Format. edition.jsonld format

Performance

The roll's performance reconstructed as Music Performance Markup, with the transcription, the score and the work file it was fitted from. performance.mpm transcription.mei score.msm work.json format

Identifiers

Every entity of the edition has an IRI under this domain. Each of them opens the edition at that entity in Roll Desk: the edition itself is https://welte225.org/, a copy is https://welte225.org/copy/<id>, a symbol read from the roll is https://welte225.org/symbol_<id>, and a hole on a copy is https://welte225.org/<id>. A segment of the performance reconstruction is https://welte225.org/mpm/<id> and opens at that segment in MPM Desk, the first eight characters of the id being enough.
