'Song' in the Bible

Then David made this song of grief for Saul and Jonathan, his son:

And the king made a song of grief for Abner and said, Was the death of Abner to be like the death of a foolish man?

I am now eighty years old: good and bad are the same to me; have meat and drink any taste for me now? am I able to take pleasure in the voices of men or women in song? why then am I to be a trouble to my lord the king?

And David made a song to the Lord in these words, on the day when the Lord made him free from the hands of all his haters, and from the hand of Saul:

Because of this I will give you praise, O Lord, among the nations, and will make a song of praise to your name.
