does the Bible have anything negative to say about music??
Not if it is to worship God.
Here are a couple of scriptures regarding music and worship of idols for you to check out.
Ezekiel 26:13
And I will stop the music of your songs, and the sound of your lyres shall be heard no more.
Daniel 3:5
that when you hear the sound of the horn, pipe, lyre, trigon, harp, bagpipe, and every kind of music, you are to fall down and worship the golden image that King Nebuchadnezzar has set up.
Daniel 3:7
Therefore, as soon as all the peoples heard the sound of the horn, pipe, lyre, trigon, harp, bagpipe, and every kind of music, all the peoples, nations, and languages fell down and worshiped the golden image that King Nebuchadnezzar had set up.
Daniel 3:10
You, O king, have made a decree, that every man who hears the sound of the horn, pipe, lyre, trigon, harp, bagpipe, and every kind of music, shall fall down and worship the golden image.
Daniel 3:15
Now if you are ready when you hear the sound of the horn, pipe, lyre, trigon, harp, bagpipe, and every kind of music, to fall down and worship the image that I have made, well and good.1 But if you do not worship, you shall immediately be cast into a burning fiery furnace. And who is the god who will deliver you out of my hands?”
