Angels play all sorts of instruments and are not limited by any means to harps. Imagine the best concert or symphony you have ever heard and multiply it, ever piece of classical music, piano, violin, and it would pale in comparison the to the beauty of heaven.

The enemy’s loss is our gain, and we rejoice in His name and presence, and make a joyful noise to Him, Psalm 100:1
I will bless the Lord at all times: His praise shall continually be in my mouth. Psalm 34:1
Sing a new song to the LORD! Let the whole earth sing to the LORD! Psalm 96:1
Praise the LORD, you strong and mighty angels, who obey His commands, who listen to what He says. Psalm 103:20 Good News
