Bhagavad Gita · 1.13

ततः शङ्खाश्च भेर्यश्च पणवानकगोमुखाः।सहसैवाभ्यहन्यन्त स शब्दस्तुमुलोऽभवत्॥

tataḥ śhaṅkhāśhcha bheryaśhcha paṇavānaka-gomukhāḥ sahasaivābhyahanyanta sa śhabdas tumulo 'bhavat

Then suddenly, conches, kettledrums, trumpets, drums, and horns all blared forth, and the combined sound was tumultuous.
