Let me tell you, with reverence and clarity, of the subtle science of accents and pronunciation as described in the sacred text. Within the tone called udātta, the notes niṣāda and gāndhāra are included; while in the anudātta, the notes ṛṣabha and dhaivata find their place. Whenever guttural sounds, sibilants, and those pronounced from the root of the tongue are encountered, they are to be understood as arising by their very nature—pronounced swiftly, distinctly, and with consonants held firm and stable. Now, let me describe for you the characteristics of these tones, one by one. A syllable, whether it carries the consonant 'ka' or 'va', can become svarita, the independent accent. Whenever the vowel 'i' is raised to udātta, you may find this sometimes in syllables like 'pa' and 'va'. Furthermore, when the vowels 'e' or 'o' arise from the combination of two udātta vowels, or when 'a' is pronounced with clarity and distinction, then whatever syllable follows an udātta in a metrical line takes on the svarita accent. Svarita also arises immediately after an avagraha, and when the vowel 'i' is joined with another 'i'. Wherever, in any tone, svarita occurs—whether the syllable stands alone or is joined with others—it is considered the primary accent at the beginning of a chant, and should be pronounced swiftly. A subtlety arises when a pause is suppressed and the sound is elided; in such cases, a blended note emerges, known as hīīgovarṇa. If, before a single raised syllable, there is any other syllable, the tradition speaks of four initial accents, referred to as kaṃṣa, puṃ, and sphuti, according to the authoritative treatise. When a word ends with 'i' and is followed by a word beginning with 'u', or when it is followed by two 'u's in the next word, three long vowels should be recognized, as well as those that emerge from the joining of syllables. If, among many raised syllables, an unraised syllable follows, or wherever two or more raised syllables are found together, certain rules apply: there is never a doubling of the letters 'r' or 'h' in any circumstance. The fourth accent is linked with the third, and the second with the first, in their proper sequence. If a preceding syllable is not the last, it should be carried forward endlessly until the following syllable reaches the end. The final letters of the consonant groups, along with 'śa', 'ṣa', and 'sa', or those joined with final letters, are to be pronounced with care. After the third and fourth accents, and the word that follows the fourth, certain sounds—anusvāra, upadhmānīya, and mūrdhanya—may occur in due order. Wherever a conjunction is seen, and a consonant appears at the end of a word, the accent is raised and extended accordingly. From such a conjunction, the following syllables are governed by the same rule. The anusvāra at the end of a word, as well as that which arises in its proper affix, must be recognized in sequence. At the beginning of a pāda, and at the beginning of a pāda following another, as well as in cases of conjuncts and avagraha, the anusvāra remains, even at the start of a pāda, without separation, at the end of a conjunct. A residual short vowel or the letter 'hṛ', or an indistinct pair at the beginning, are to be pronounced as they are. Whatever is low in tone remains low; whatever is in a cluster is also pronounced in the low tone. Words such as 'priya', 'dūta', 'ghṛta', 'citta', and 'ati' are always to be pronounced in the low tone. Among the hundreds of words, and among the pure, the recitation rises from the low to the high tone. The syllable 'viśvānara' and the letter 'o' are to be pronounced with the svarita accent, and so too with the rest, O noble listeners. Wherever a double accent is applied, a short vowel should be drawn out as if it were long. The measure of time for a syllable—the mātrā—is said to be the time it takes to blink an eye; others say it is as swift as a flash of lightning. Thus, the accents of the Ṛk, or those with equal conjunction, are declared by some to follow these very principles. In this way, the ancient science of pronunciation and accent is preserved and passed down, ensuring the Vedic recitation remains pure and precise for all time.
