The Mosaic laws had 613 rules, many of which spelled out in exact detail how NOT to behave like the nations surrounding them. Rules about diet and dress codes and all kinds of things. But when it came to music, absolutely nothing is forbidden. They used the same musical instruments and styles as anyone else. The only difference is that they used their music to worship the one true God and to celebrate life.
Music is the language of the heart.
The language itself is neither holy or unholy. If the heart is profane, then what comes out of the heart is profane. If the heart is pure, then what comes out of the heart is pure. It's not the sound of words that makes them holy. It's the intention and motive behind the communication.
