Anūcāna (True Learning), the Vedāṅgas, and Śikṣā: Svara, Sāmavedic Chant, and Gandharva Theory
अंतरस्वरसंयुक्तः काकलिर्यत्र दृश्यते । तं तु साधारितं विद्यात्पंचमस्थं तु कैशिकम् ॥ ५५ ॥
aṃtarasvarasaṃyuktaḥ kākaliryatra dṛśyate | taṃ tu sādhāritaṃ vidyātpaṃcamasthaṃ tu kaiśikam || 55 ||
ที่ใดเสียงกากลีปรากฏร่วมกับเสียงคั่นกลาง พึงรู้ว่าเป็นแบบ ‘สาธาริต’; และเมื่อวางอยู่ที่เสียงปัญจมะ จึงเรียกว่า ‘ไกศิกะ’.

It emphasizes that precise intonation (svara) is part of dharma: mantra power and clarity of meaning depend on correct tonal knowledge taught in Vedanga-Śikṣā.
Bhakti is supported by right practice: when hymns and mantras are sung/recited with correct swaras, devotion becomes disciplined and the offering (stuti/japa) is considered properly formed.
Vedanga-Śikṣā: it gives a technical rule for identifying and naming tonal variants (kākali as sādhārita; and kaiśika when positioned on pañcama), useful for accurate chanting and musical-phonetic tradition.
