(b nr St Gallen, Switzerland, c 840; d St Gallen, April 6, 912). Monk of the Benedictine abbey of St Gallen , poet and scholar . The Casus monasterii Sancti Galli of Ekkehard IV of St Gallen (c 1040) paints a lively picture of the monastery school while Notker and his fellow monks Ratpert and Tuotilo were active. Although the two latter are known to have composed music, Notker (called Balbulus, ‘the stammerer’) seems to have been only exceptionally active as a composer of chant, if at all. The work for which he is best known in the history of music is the Liber hymnorum, a collection of texts set to the melodies of liturgical sequences, organized in a cycle for the Church year. This was completed in 884. Other important works include a Vita Sancti Galli (life of St Gallus) in verse, the Gesta Karoli (the deeds of Charlemagne), and a martyrology....
