IDEM – Integrated Database for Early Music

IDEM is an interdisciplinary and multifaceted database of manuscripts and printed books that are relevant to the Alamire Foundation's research and activities. It therefore especially focuses on the musical heritage of the Low Countries from the early Middle Ages until 1800.

IDEM contains digital images of manuscripts and prints digitized by the Alamire Digital Lab, the high-technology photography centre of the Alamire Foundation (KU Leuven – Musicology Research Unit). Its state-of-the-art equipment allows musical sources to be photographed following the strictest standards and quality requirements.

The core database is complemented by interrelated sub-databases that enable the consultation and study of manuscript and printed sources from multiple perspectives. IDEM will eventually contain information about every aspect of the manuscripts and books concerned, including their physical characteristics, their content and illumination, as well as recordings, editions and so-called 'fake-similes' (adapted versions of the original images, facilitating performance from the original notation).

IDEM is thus designed to be an online, freely accessible platform and tool for the preservation, study, and valorisation of the music heritage of the Low Countries.

July 2024 - In the spotlight: A-Wn Mus.Hs. 15496

Pierre de La Rue was one of the leading composers of his time and certainly one of the most prolific. From 1492, he became a member of the Habsburg-Burgundian court chapel. Not surprisingly, many of his compositions were included in the manuscripts produced for the court under the direction of the music scribe Petrus Alamire. Four codices are even devoted solely to works by this Franco-Flemish polyphonist. Mus.Hs. 15496, preserved today in the Österreichische Nationalbibliothek, is one of them.

The choirbook contains seven polyphonic masses by de La Rue, opening with his five-voice Missa Alleluia. This polyphonic mass is underpinned by a borrowed melody that La Rue insistently repeats throughout the composition as 'cantus firmus', mostly in the tenor. The text 'Alleluia' was copied in red below the tenor part, further highlighting the strict treatment of the cantus firmus in this mass. The opening pages also immediately give us an insight into the manuscript’s genesis. The right-hand page features the Habsburg-Burgundian coat of arms and the red inscription "Karolus Archidux Austrie, Dux Bourgundie, Princeps Castelle": “Charles, Archduke of Austria, Duke of Burgundy, King of Castile”. When Charles V was officially declared of age on 5 January 1515, he had the Low Countries under his rule and became king of Spain. His grandfather, Maximilian I, whose imperial emblem appears later in the manuscript, may have ordered the choirbook to mark this occasion.
