A point of melodic and metric closure gen.

[Anastacia1801]

Пожалуйста, помогите перевести. "A point of melodic and metric closure"
Слово встречается в следующем контексте The first exposure of the lyrics was presented without interruption so the children could hear the lyrics in their entirety. Subsequent exposures involved breaking each phrase down into
two sections: A and B. A point of melodic and metric closure between sections A and B in the phrases allowed for a natural separation of the sections. The same point of separation was used in the spoken condition. Section A of each line always contained 5 syllables and was sung to the same melodic contour. Each line was taught using a ‘repeat-after-me’ method whereby the teacher stopped at the end of each section in order for students to repeat back the lyrics. Lines were then built back to their whole and repeated again. At the end of each line, the teacher translated the target terms from English into Spanish using the direct paired-associate method. In the sung condition, the song was practiced with a guitar accompaniment.
Заранее спасибо

Момент завершения мелодики и метрического ряда текста между частями А и Б во фразах позволял органично разделять эти части.

точка мелодической и ритмической остановки.
"размерная остановка" - точнее, но не канает)))
