Is it possible that the syntagmatical sequence of cantillation signs used in the Babylonian tradition determines the coherence of the melodic patterns of Avinu Malkeinu, the main Jewish prayer sung in the communities of Western Asia? If so, what exactly distinguishes the prayer chant from similar patterns in the Torah cantillation? We will try to find the answer to these questions based on the musical transcription (G. Shamilli) of the audio recording of the legendary cantor Isaac Maggioro (1918-2008).
