Karl Hoyer (1891-1936) was a highly regarded pupil of Max Reger and Karl Straube the Kantor of St. Thomas’s Church Leipzig. He held several positions including that of professor at the famous Institute for Church Music in Leipzig. For a long time his Chorale Preludes Op.57 were only available in libraries or second hand bookshops but the publication of the third of a four-volume edition makes another part of this important collection available once more. These pieces are characterised by formal variety brevity and are mostly modest in their technical demands. They were extremely well-known amongst organists duringHoyer’s lifetime a period which marked the transition from late Romanticism to that of the German Organ Movement of the 1920s. In comparison with the first edition the keys correspond with those in the “Evangelisches Gesangbuch” and “Gotteslob (Protestant and Catholic hymnbooks)”. Each volume includes appropriate indices for practical use in “Protestant or Catholic” churches. - Chorale preludes from the period between late Romanticism and the beginnings of the German Organ Movement- Appropriate keys for the “Evangelisches Gesangbuch” and “Gotteslob (Protestant and Catholic hymnbooks)”
