'Singing' in the Bible

Beside their manservants and their maidservants, of whom there were seven thousand three hundred thirty and seven: and they had two hundred forty and five singing men and singing women.

And at the dedication of the wall of Jerusalem they sought the Levites out of all their places, to bring them to Jerusalem, to keep the dedication with gladness, both with thanksgivings, and with singing, with cymbals, psalteries, and with harps.
