Well, that may be tough. There may be Bible verses that can help support music, but I don’t think so. The reason is that one group I know of which denies music does so on the basis of what they call “respecting the silence of God.” This is basically what Ulrich Zwingli did in the 1500s and what led him to destroy all the church organs in Switzerland.
The idea is that if a practice is not specifically permitted by Scripture, it is not allowed because one must always respect that God taught us everything He wished to. In their minds, if we do things which aren’t in the Bible, we are acting as though God didn’t have the ability to teach us everything He wanted.
The biggest problem with this idea is obviously that the Bible never says it, so it is completely self contradictory, even moreso than Sola Scriptura is. The other biggest problem is that all the explanations I have ever seen of it are so strong that if we followed this principle we would not be allowed to do things like listen to the radio, wear wristwatches, or play baseball because the Bible never tells us we are allowed to. In fact, the Bible never tells us it’s permitted to read the Bible in worship, or to give sermons, or to teach in worship, so they have a whole slew of problems.
If you get some other verses, I will be happy to figure out what’s wrong with them.
