Besides this, the cantor was naturally the instructor of music in the community, and at certain times he took the novices and trained them in the proper mode of ecclesiastical chanting and in the traditional music of the house. In many monasteries he had also to teach the boys of the cloister-school to read, and the exasperating nature of this part of his office may be perhaps gauged from a provision inserted in some statutes, that he was on no account to slap their heads or pull their hair, this privilege being permitted only to their special master.

On account of the cantor's care of the church services and the necessary labour entailed thereby upon him, some indulgence was generally accorded to him in regard to his attendance at the parts of the Divine Office where his presence was not specially required. He was, however, forbidden to absent himself from two consecutive canonical hours, and was not to stay away from Matins, Vespers, or Compline. On Saturdays, like the rest, he had to wash his feet in the cloister.

So much with regard to the duties of the precentor, as chief singer of the monastery. He was also the librarian, or _armarius_; the two offices, somewhat strangely, perhaps, to our modern notion, always going together. In this capacity he had charge of all the books contained in the aumbry, or book-cupboard, or later in the book-room, or library. Moreover, he had to prepare the ink for the various writers of manuscripts and charters, etc., and to procure the necessary parchment for book-making. He had to watch that the books did not suffer from ill use, or misuse, and to see to the mending and binding of them all. As keeper of the bookshelves, the cantor was supposed to know the position and titles of the volumes, and by constant attention to protect them from dust, and injury from insects, damp, or decay. When they required repair or cleaning, he was to see to it; and also to judge when the binding had to be repaired or renewed. For the purpose of thus renovating the manuscripts under his care, he had, of course, frequently to employ skilled labour. At such times he received an allowance of food for the workmen engaged "on cleaning the bindings of the choir books," etc. Special revenues also were at his disposal "for making new books and keeping up the organs."
