|Chapter 1: Observing the Armies on the Battlefield of Kurukshetra|
tatah sankhas ca bheryas ca
sa sabdas tumulo 'bhavat
After that, the conchshells, bugles, trumpets, drums and horns were all suddenly sounded, and the combined sound was tumultuous.
The sounds are described as "tumultuous." They reflect a state of discord, confusion and dis-harmony on the side of the Kauravas. On the other hand, as we will see later, the sounds of the conches on the Pandavas side are described as transcendental.
