Upon the staff of the School the Cantor ranked third after the Rector and Sub-Rector, and took a share in the general instruction of the scholars. Class III. went to Bach for Latin lessons, a duty which the Council eventually permitted him to fulfil by deputy. Singing classes were held by the Cantor on three days of the week, Mondays, Tuesdays, and Wednesdays, at nine and noon, and on Fridays at noon. His instruction in singing was given to the four upper classes only. On Saturday afternoons the Cantata was rehearsed. Once in four weeks the Cantor took his turn to inspect the scholars. Like the other masters, he was required to conform to the regulations of the School House, in which he lived. He rose at five in summer, at six in winter, dined at ten and supped at five in the afternoon. Holidays were numerous. A week’s vacation was given at the Easter, Michaelmas, and New Year Fairs. At Midsummer the School had a month of half-holidays. Whole holidays were given on the birthdays of the four upper masters. There were no morning lessons on Saints’ Days, on the occasion of funeral orations in the University Church, and on the quarterly Speech Days. Hence, though Bach’s office carried large responsibility, it left him considerable leisure for composition. As Cantor Bach had an official residence in the left wing of the School House. In 1723, the Cantor’s wing was of two storeys only, dwarfed by the greater elevation of the main edifice and under the shadow of the church. Bach brought to Leipzig four children of his first marriage, and his second wife, Anna Magdalena, presented him with a son or daughter annually from 1723 to 1729. The accommodation of the Cantor’s lodging therefore rapidly became inadequate. In the spring of 1731 Bach found a house elsewhere while an additional storey was added to it, which provided a new music-room, a good-sized apartment whence a passage led to the big schoolroom in the main building. The new wing was formally opened and dedicated on June 5, 1732, when Bach’s secular Cantata Froher Tag, verlangte Stunden was performed; the libretto being by his colleague Winkler. From thenceforward till his death eighteen years later Bach’s occupancy was not disturbed. The wing continued to be the official residence of the Cantor until the School moved to the suburbs of the city in 1877.
