Chronicles On The Singers

It is clear that praising G-d by singing is a delight in His ears.

But, it has to be in a genuine way, and must be evident in your words, action and way of life most importantly.

“The Singers”

David and the officers of the service corps set aside the sons of Asaph, Heman and Jeduthun who prophesied while using harps, lyres, and cymbals. Their number of workmen required for their service, was:
25:1
… giving thanks and praise to Hashem.
25:3
All these were under the auspices of their father for song in the Temple of Hashem, with cymbals, lyres, and harps for the service of the Temple of God, …
:6
… trained in the singing of songs for Hashem, all of them with skill, …
:7
He, his brothers and sons were twelve.

1 Then David and the generals of the army separated for the service of the sons of Asaph, Heman, and Jeduthun, who prophesied with harps, with lyres, and with cymbals, and the number of those men expert in their work, according to their service, was:
2 Of the sons of Asaph: Zaccur, and Joseph, and Nethaniah, and Asarelah, the sons of Asaph through Asaph, who prophesied according to the direction of the king.
3 Of Jeduthun the sons of Jeduthun: Gedaliah, and Zeri, and Isaiah, Hashabiah, and Mattithiah-six, beside their father Jeduthun with the harp, who prophesied with [songs of] thanksgiving and praise to the Lord.
