In sacrificial works there is Monotony, except in japa (silent repetition of a formula), nyūṅkha vowels (16 sorts of om) and the sāma Vedas.,
In \sacrificial works\ or on occasions of sacrifice, the mantras of the Veda are recited in Ekasruti or monotony. But on occasions of ordinary reading, the mantras are to be recited with their proper three-fold accents.
\Japa\ is the repetition of mantras, and their recitation in a low voice or whisper. Nyunkha is the name of certain hymns of the veda, and the names of 16 sorts of \Om.\ Some of these are pronounced with udatta and others with anudatta accent. Samas are songs, or the musical cadence in which some vedic hymns are to be uttered. As:- अ॒॒ग्निर्मूद्धादि॒॒वः क॒॒कुत्पतिः॑ पृथि॒॒व्या अ॒॒यम् । अपाम् रेतांसि जिन्वतो३ म् (Rig Veda VIII. 14. 16).
When a mantra is recited as a japa, then it must be pronounced with accents :- As समा॑ग्ने वर्चो॑ विह॒॒वेष्वं॑स्तु (Rig Veda X. 128. I).
When not employed on occasions of sacrifice, but are ordinarily read, the mantras must have their proper accent, and there will be no Ekasruti.
In the sama chanting, the mantras should have their accent, there can be no Ekasruti there. As ए३विस्वं समत्रिणं दहा३. Here there is no Ekasruti.,
