Enrique Granados’s Duo-Art piano-roll performance of his Danza española no. 5 (Andaluza), made some 20 years after the piece was published, illuminates much about late-Romantic piano performance practices.
Transcription and analysis of this piano roll illustrate the disparity between score and performance. Granados added and changed notes, ornaments, articulations, and chords. He also altered many rhythmic values, desynchronized melody and accompaniment, rolled chords at will, and introduced drastic tempo changes not indicated in the score. His performing style thus reflects a personal approach to the piano that lies well within the broader context of the Romantic performance tradition.
This according to “Piano-roll recordings of Enrique Granados: A study of a transcription of the composer’s performance” by Anatole Leikin (Journal of musicological research XXI/1–2 [January–June 2002] pp. 3–19).
Today is Granados’s 150th birthday! Below, the recording in question.
