The earlier version, entitled “Cross-Repertoire Motifs in the Liturgical Music of Ashkenazi Tradition,” was presented at the World Congress of Jewish Studies, Jerusalem, 2013. This article is an expanded and elaborated version of that paper.
The article deals with research of the "Adonai Malach" Steiger using 30 melodies representing an existing tradition. "Adonai Malach"'s scale, motives, the motives' function, placement and the Steiger's "ethos" are all examined. The Steiger proves to be an extraordinary phenomenon in European music but there is an obvious similarity to the melodic structure of Eastern music in the past and present.
This article translates and explains two manuscripts originally in Arabic written in Hebrew letters one of which originates from Iraq in the late 10th century. They discusses different aspects of music, list melodic and rhythmic modes and discuss Pythagorean and NeoPythagorean ideas about music.
