Samuel Barber, Mutations from Bach
Royal Scottish National Orchestra, Marin Alsop, conductor
Mutations from Bach, compiled and arranged for brass ensemble and timpani by Samuel Barber, is made up of a short sequence of transformations of the plain-song, Christe, du Lamm Gottes (Christ, Thou Lamb of God). The original tune is first heard as harmonized by Joachim Decker in 1604, and then in Johann Sebastian Bach’s harmonization from Cantata No. 23 (1717-1723). Later, it is heard in canon at the twelfth, taken from the Chorale Prelude No. 21 from Bach’s Orgelbüchlein (1708-1717), then quoted from the recitative section Ach, gehe nicht vorüber, from the earlier Cantata No. 23. The work concludes with a restatement of the original version of the chorale.
