'Harpists' in the Bible

I also heard a sound coming out of heaven like the sound of many waters and like the sound of loud thunder. Now the sound I heard was like that made by harpists playing their harps,

And the sound of the harpists, musicians, flute players, and trumpeters will never be heard in you again. No craftsman who practices any trade will ever be found in you again; the noise of a mill will never be heard in you again.
