The first mention of music in the Bible is in Genesis

Genesis 4:21: And his brother's name was Jubal: he was the father of all such as handle the harp and organ.

Music formed an integral part of Old Testament life. It was central in Israel’s worship (1 Chron 15:27-28 and Neh 12:45-47). In 1 Chronicles, King David assigned duties to the priests, musicians and singers, divisions of the porters, treasurers and other officials (1 Chron 25:1; 9:22-29). These people were entrusted with responsibilities for worship in the Temple.

1 Chronicles 15:27-28: And David was clothed with a robe of fine linen, and all the Levites that bare the ark, and the singers, and Chenaniah the master of the song with the singers: David also had upon him an ephod of linen. Thus all Israel brought up the ark of the covenant of the LORD with shouting, and with sound of the cornet, and with trumpets, and with cymbals, making a noise with psalteries and harps.
