This the Greek version (below) of the chant Kyrie Ekekraxa, the well known composition by Petros Byzantios in the 19th-century Constantinople (now Istanbul) performed in 2012 by fr. Makarios Haidamous. The audio recording was first published in Amine Beyhom’s book on Byzantine chant in 2015 (see http://foredofico.org/CERMAA/archives/584).
As with other CERMAA animated analyses, the upper part offers a general view of the analysis (with two dashed lines for the tonic and octave pitches) while the lower part shows the detailed analysis which includes, in this case, an overprint of the Byzantine scale of the 1881 (Second) Reform of Byzantine chant.
