After opening Ark to get sefer Torah on Shabbos and Yom Tov in Ashkenazy custom many congregations sing verses:
כִּי מִצִּיּון תֵּצֵא תורָה. וּדְבַר ה' מִירוּשָׁלָיִם: בָּרוּךְ שֶׁנָּתַן תּורָה לְעַמּו יִשרָאֵל בִּקְדֻשָּׁתו:
What is a reason for a double repetition of phrases: כִּי מִצִּיּון תֵּצֵא תורָה and בָּרוּךְ שֶׁנָּתַן תּורָה, i.e. what was the intention of the composer of the tune?
The fact that the word תּורָה is repeated as תּורָה-תּורָה when singing בָּרוּךְ שֶׁנָּתַן sounds as if it refers to both written and oral Torah in opposition to Reform not accepting the oral Torah. Why would some chazanim avoid making these repetitions?
