'Music' in the Bible

in unison when the trumpeters and the singers were to make themselves heard with one voice to praise and to glorify the Lord, and when they lifted up their voice accompanied by trumpets and cymbals and instruments of music, and when they praised the Lord saying, “He indeed is good for His lovingkindness is everlasting,” then the house, the house of the Lord, was filled with a cloud,

The priests stood at their posts, and the Levites also, with the instruments of music to the Lord, which King David had made for giving praise to the Lord—“for His lovingkindness is everlasting”—whenever he gave praise by their means, while the priests on the other side blew trumpets; and all Israel was standing.
