If music began in the heart of God it is fitting that it should be offered back to Him.
[God] will rejoice over you with singing. Zephaniah 3:17
Music is referred to many times throughout the scriptures and musical instruments are rightfully used to praise the Creator.
Psalm 92: v1-3 NIV
It is good to praise the Lord and make music to your name O Most High, to proclaim your love in the morning and your faithfulness at night, to the music of the ten-stringed lyre and the melody of the harp.
Psalm 104: 33
I will sing to the Lord all my life; I will sing to my God as long as I live.
Psalm 146: 2
I will praise the Lord all of my life; I will sing praise to my God as long as I live.
Worship the Lord with gladness; come before him with joyful songs.
How good it is to sing praises to our God, how pleasant and fitting to praise him!
Psalm 42: 8
By day the Lord directs his love, at night his song is with me – a prayer to the God of my life.
Praise the Lord with the harp; make music to him on the ten-stringed lyre. Sing to him a new song; play skilfully, and shout for joy.
Praise him with the sounding of the trumpet,
praise him with the harp and lyre,
praise him with timbrel and dancing,
praise him with the strings and pipe,
praise him with the clash of cymbals,
praise him with resounding cymbals.
Let everything that has breath praise the LORD.
