These Eight Video-analyses of the scales of Byzantine chant (for the scales of the Eight modes) are proposed on a dedicated main page. The analyses come originally from the book of Amine Beyhom Théories et pratiques de l’échelle dans le chant byzantin arabe : Une approche comparative et analytique proposant une solution inédite pour le système théorique de Chrysanthos le Madyte and were edited for video.
Four Lebanese cantors of Byzantine chant – Fr. Nicolas Malek, Fr. Makarios Haidamous, Joseph Yazbeck and a cantor who preferred to remain anonymous – accepted to record (among other performances) the scales of the eight canonical modes of their liturgical chant for research purposes. Each of them is a renowned soloist and choir director in Lebanon.

The complete results of the analyses of these recordings are proposed in the aforementioned book, while particular results concerning the first mode were presented on various occasions in Greece and in Cyprus, but also in France, Tunisia and in Lebanon.
The analyses in the videos are based on these presentations, which in turn were based on power point animations proposed in the aforementioned book.
Each video comprises a short theoretical introduction contextualizing the scales of the current mode within the general frame of the 19th-Century Second Reform of Byzantine chant.

Moreover, the first video (for the First mode) features a General Introduction which explains shortly:
- The solmization of the Byzantine – and equivalences between Byzantine and Western – degrees of the scale

- The accidentals used in the theory of the Second Reform (and in the Western/Byzantine notation proposed by the author)

- The scores and literal notations

- (And) Explanations about the graphic representation of the results

The videos on the main page are in High resolution, and also available on the YouTube Channell of CERMAA. An alternate, Low resolution version is proposed for each mode (and the Intro) in a dedicated page.
