Бах Chorale Prelude 'Machs mit mir, Gott, nach deiner Güt', BWV 957

Machs mit mir, Gott, nach deiner Güt, BWV 957 is a chorale prelude for organ by Johann Sebastian Bach, catalogued as either BWV 957 or  BC K191. It is a single movement work in G major, first published in 1880. For a long time it was though to be a fugue for harpsichord, though now it classified as a chorale prelude for organ (that features a fugato). A chorale prelude is a short composition for organ using a chorale as its basis. The liturgical function of a chorale prelude in the Baroque period is still debated.
