Charles Ellicott Commentary Isaiah 14:11

"Thy pomp is brought down to Sheol, [and] the noise of thy viols: the worm is spread under thee, and worms cover thee." — Isaiah 14:11 (ASV)

Your pomp is brought down to the grave. Literally, to Sheol, as in Isaiah 14:9. The “pomp” is the same as the “beauty” of Isaiah 13:19.

The noise of your viols. —Perhaps harps, or cymbals, representing one of the prominent features of Babylonian culture (Daniel 3:5). The singers see, as it were, all this kingly state mouldering in the grave, maggots and worms (the two words are different in the Hebrew) taking the place of the costly shawls and carpets on which the great king had been accustomed to rest.
