In ancient times, the revered sages devoted themselves to the practice of righteousness, and among them, one who had truly studied the sacred texts was held in the highest esteem. Eager to understand the essence of such greatness, a disciple approached his learned teacher and asked, “Please tell me that act or knowledge by which one becomes skilled in all the Vedas and their branches, for I am keen to hear and learn.” The wise teacher replied, “Those who are truly knowledgeable grasp not only the Vedas but also the science of meter and the six essential limbs of debate. It is through the four Vedas alone that the principles of dharma are determined. One who has mastered these Vedas prevails, regardless of how many other texts one may study—without this mastery, even millions of texts are insufficient.” He then addressed his disciple with warmth, “Among us, you are known for your learning in these branches, O bestower of honor. Now, listen as I briefly convey to you the certain essence of these teachings, as proclaimed by the knowers of the Vedas.” He continued, “At the conclusion of any ritual, the science of tones—how the sacred words are intoned—must be especially observed. In the Sāma chants, it is important to understand that the intervals between tones are threefold. If these instructions are neglected or misunderstood, the chanting becomes discordant. Such faulty speech can destroy the sacrificer, just as a mistake in tone once led to the ruin of Indra’s enemy, struck down like a thunderbolt.” “These precise recitations are performed at the Soma sacrifices. In the Sāma Veda, the interval between tones is sometimes half. If you are unable to express these distinctions clearly, know that this is the rule for recitation. In both the Ṛgveda and the Sāmaveda, the first tone must be pronounced. The tone called ‘pārthiva’ is a blend of high and medium pitches. The second and subsequent tones, ending in the low pitch, are found in the Taittirīya tradition, which recognizes four tones. O sage among sages, the Sāma singers produce both the low and high tones, and in the Śatapatha tradition, these two tones belong to the Vājasaneyins. Thus, the practice of these various tones is universal across all the Vedas.” “The branch of the Sāmaveda, though concise in text, is abundant in meaning and is considered supreme among the Vedas. It is pure, purifying, and auspicious, as has been declared to you. The musical scale is based on seven tones, and there are twenty-one recognized modes of modulation. The tones are named Ṣaṅja, Ṛṣabha, Gāndhāra, and Madhyama. Among these, Ṣaṅja, Madhyama, and Gāndhāra are known as the grāmas, or musical scales. The three positions of the grāma are Svarga, Abhra, and Gāndhāra.” “In the Madhyama grāma, there are twenty modes, and in the Ṣaṅja grāma, there are fourteen. The names of various modes include Nadī, Viśālā, Sumukhī, Citrā, Citravatī, and Mukhā, as well as Āpyāyinī, Viśvabhṛtā, Candrā, Hemā, and Kapardinī. In the Ṣaṅja scale, the mode Uttaramandrā is found; in the Ṛṣabha scale, Abhirūhatā. In the Madhyama scale, Sauvīrā and Hṛṣikā are found in the fifth note. In the Niṣāda scale, Rajanī is recognized. There are seven mūrchanās, or melodic arrangements, of the Ṛṣis, and likewise, seven for the Pitṛs and for the Yakṣas, without doubt.” “Of these, the Ṣaṅja scale is pleasing to the gods, while the Ṛṣabha scale pleases the Ṛṣis. The fifth note delights the gods, ancestors, and Ṛṣis alike. The qualities and modes of song are tenfold, which include kākasvara (the crow’s tone), mūrddhagata (arising from the head), and those lacking proper position. When the song is disturbed or lacks rhythm, these are counted among the fourteen faults of singing.” “In the end, the fortunate desire sweetness in their song, while others may seek elevation. Thus, the science of Vedic chant and song is both subtle and profound, requiring both knowledge and devotion for its mastery.
