The famous St Gall Abbey Library provides a home for manuscripts which are vital not only for specialised research into the liturgical music at St Gall, but also for general research into the Mediaeval period: this collection includes examples of early repertoire relating to Gregorian chants such as the socalled St Gall Cantatorium (around 920), and for the younger categories trope and sequence, the St Gall troperssequentiaries dating back to the period between the 10th and 12th centuries. This recording focuses on the works of Notker: the best-known and most perfect creations of the great poet-musician from St Gall. Emphasis is given to the sequence form with which Notker’s name is particularly linked, a supplementary entry in the necrology of the Gallus monastery on the occasion of his death on 6 April 912 reads: Qui sequentias composuit.

The ensemble Ordo virtutum was founded by the musicologist Professor Dr. Stefan Morent, and specialises in the music of the Middle Ages. It is primarily active in the field of medieval music drama, but also in smaller chamber music groups. It aims to combine performance with musicological research, in order to reveal the musical world of medieval Europe.
