These pieces are known as "Arnstädter Gemeindechoräle" due to their supposed association with the proceedings of the Arnstadt Consistory on 21 February 1706 in which Bach, organist of the Bonifacius Church, was reproved "for having hitherto made many curious variations in the chorales and mingled many strange notes in them, with the result that the congregation has been confused".
