verb
intone
in-TOHN/ɪnˈtəʊn/
To say or recite in a solemn, chant-like voice.
The priest intones a blessing as the congregation bows.

Etymology
The combination of 'in' and 'tone' meant singing according to tone. Intoning carries that musical quality into recitation: words are delivered with a chant-like pitch rather than the inflections of ordinary conversation.
