A few quotes from the Rabbi on 'Customs of Israel'
in which he explains why Torah is to be read melodically, so that it can be inscribed and retained in our hearts
It does not suffice to engage in Torah through reflection. It should be voiced, with a melody and tune, as the Talmud says, 'concerning anyone who reads without a melody or studies without a song, the verse states: So too I gave them statutes that were not good...' So that when it is fully enunciated with a holy melody…it becomes inscribed in the person's heart and is bequeathed to him as a gift.
