score-viewer
An MEI score viewer for reading and listening to critical editions.

score-viewer is a React component for reading and listening to scores encoded in MEI and rendered with Verovio. It can also be embedded in any page with an <iframe>. It is free software, under the MIT license.
- Score, paginated, with zoom, section titles, a choice of verses, original clefs, harmonic analysis and undoing the encoded transposition.
- Critical apparatus. Editorial interventions are highlighted by type, and readers can switch between the readings of a variant.
- Audio synchronized with the score: notes are animated while they sound and the score turns its own pages.
- Facsimile of the sources beside the score. When the MEI links notes to the images, the facsimile follows the music while it plays.
- Texts: introduction, poem and notes. Interface in English and Spanish.
It is the reading interface of the digital critical edition of the Cancionero de Miranda, a songbook of 77 tonos humanos copied at the Royal Chapel in Lisbon in the late seventeenth century. Its design was presented in the paper The Cancionero de Miranda Edition: Leveraging Open Source Technologies for Multi-Modal Music Publication, at the 12th International Conference on Digital Libraries for Musicology (DLfM 2025).
