on (C, if the melos starts there) or one step lower on the , the called "grave echos" (a kind of B flat). It is definitely exaggerated to pretend that one has "deciphered" Kondakarian notation, which is hardly true for any manuscript of this period. But even considering the difference of about at least 80 years which lie between the Old Byzantine version of Slavic scribes in Novgorod (second row of the kondakar's) and the Middle Byzantine notation used by the monastic scribes of the later Greek manuscripts, it seems obvious that all three manuscripts in comparison did mean one and the same cultural heritage associated with the cathedral rite of the Hagia Sophia: the melismatic elaboration of the truncated kontakion. Both Slavonic kondaks follow strictly the melismatic structure in the music and the frequent segmentation by kola (which does not exist in the Middle Byzantine version), interrupting the conclusion of the first text unit by an own kolon using with the asmatic syllable "ɤ". Concerning the two martyre princes of the Kievan Rus' Boris and Gleb, there are two kondak-prosomoia dedicated to them in the Blagoveščensky Kondakar' on the folios 52r–53v: the second is the prosomoion over the kondak-idiomelon for Easter in glas 8, the first the prosomoion Въси дьньсь made over the kondak-idiomelon for Christmas Дева дньсь (Ἡ παρθένος σήμερον) in glas 3. Unlike the Christmas kontakion in glas 3, the Easter kontakion was not chosen as model for the kontakion anastasimon of glas 8 (). It had two other important rivals: the kontakion-idiomelon Ὡς ἀπαρχάς τῆς φύσεως (ꙗко начатъкы родоу) for All Saints, although an enaphonon () which begins on the lower fourth (), and the prooimion Τῇ ὑπερμάχῳ στρατιγῷ (Възбраньноумоу воѥводѣ побѣдьнаꙗ) of the Akathistos hymn in (which only appears in Greek kontakaria-psaltika). Even among the notated sources there was a distinction between the short and the long psaltikon style which was based on the musical setting of the kontakia, established by Christian Thodberg and by Jørgen Raasted. The latter chose Romanos' Christmas kontakion Ἡ παρθένος σήμερον to demonstrate the difference and his conclusion was that the known Slavic kondakar's did rather belong to the long psaltikon style. The era of psaltic art and the new mixed rite of Constantinople There was a discussion promoted by Christian Troelsgård that Middle Byzantine notation should not be distinguished from Late Byzantine notation. The argument was that the establishment
