Ioannes Koukouzeles, the maistor, does not alter the stichera in his anagrammatismoi [the more deliberate compositions of a sticheron kalophonikon about the final section of a certain sticheron which usually also changed its text and reworked its melodic structure], but follows them step by step, although, like composers now, he was entirely able (indeed he was much more able) to create his own original chants which had nothing in common with their prototype stichera [the simple sticheron as it was traditionally notated in the books of the sticherarion]. But, had he acted thus, he would neither acted correctly nor would he have thought that he had interpreted the science of composition befittingly. Therefore, he follows the path of the old stichera precisely and does not alter them at all, obeying the rules of the science.
