J. S.Bach, Partita 1&2, O Gott, du frommer Gott, BWV 767
O God, thou righteous God
This is probably one of Bach's earliest major organ works (that’s why I recorded it, but my old fingers couldn’t play those nice ”ornamentations, mordent”). The chorale partitas is a special form of chorale arrangement, as the chorale (or hymn) serves as the starting point for a series of variations. It is supposed that they originated in his teens and may have been revised later on. Could Bach have made this as a teenager? Unbelievable… - Wow!
