the samoglasni (idiomela) like in case of Iliya's book. Since the 12th century, there are also Slavic stichirars which did not only include the samoglasni, but also the podobni provided with znamennaya notation. A comparison of the very first samoglasen наста въходъ лѣтоу ("Enter the entrance of the annual cycle") in glas 1 (ἐπέστη ἡ εἴσοδος τoῦ ἐνιαυτοῦ echos protos, SAV 1) of the mineya shows, that the znamennaya version is much closer to fita (theta) notation, since the letter "θ =" corresponds to other signs in Coislin and a synthetic way to write a kratema group in Middle Byzantine notation. It was obviously an elaboration of the simpler version written in Coislin: The Middle Byzantine version allows to recognise the exact steps (intervals) between the neumes. They are here described according to the Papadic practice of solfège called "parallage" (παραλλαγή) which is based on echemata: for ascending steps always kyrioi echoi are indicated, for descending steps always echemata of the plagioi echoi. If the phonic steps of the neumes were recognised according to this method, the resulting solfège was called "metrophonia". The step between the first neumes at the beginning passed through the protos pentachord between kyrios (a as transcription for α') and plagios phthongos (D as transcription of πλα'): a—Da—a—G—a—G—FGa—a—EF—G—a—acbabcba. The Coislin version seems to end (ἐνιαυτοῦ) thus: EF—G—a—Gba (the klasma indicates that the following kolon continues immediately in the music). In znamennaya notation the combination dyo apostrophoi (dve zapĕtiye) and oxeia (strela) at the beginning (наста) is called "strela gromnaya" and obviously derived from the combination "apeso exo" in Coislin notation. According to the customs of Old Byzantine notation, "apeso exo" was not yet written with "spirits" called "chamile" (down) or "hypsile" (up) which did later specify as pnevmata the interval of a fifth (four steps). As usual the Old Church Slavonic translation of the text deals with less syllables than the Greek verse. The neumes only show the basic structure which was memorised as metrophonia by the use of parallage, not the melos of the performance. The melos depended on various methods to sing an idiomelon, either together with a choir or to ask a soloist to create a rather individual version (changes between soloist and choir were at least common for the period of the 14th century, when the Middle Byzantine sticherarion in this example was created). But the comparison clearly reveals the potential (δύναμις)
