Is one required to recite Kriyat Shema with the tune of Torah reading? I know it says so in Talmidei Rabbenu Yonah on the Rif Brachoth 8b, however, as someone who learned Hebrew later in life, it is difficult for me to focus on precise pronunciation with the cantillation. Obviously, it is the ideal, but is it a halachic requirement?
The Mishnah Berura 61:38 says clearly that one shouldn’t say with the cantillations if it will take away from his concentration
