At Jesus times, or maybe even way before that, God's people used many different instruments.

The Bible has a lot of mentions of various musical instruments such as tambourine (or something like it), harplike instruments, and probably many other different instruments that I missed. You will find it a lot of them in David's Psalms in the old testament. And David was called by God as a man after His own heart. David was a special man to God and many of his worship songs are forever enshrined in the Bible. David was probably in today's times would have played a lot of the contemporary worship styles since he uses so many music instruments.

Now I am not kidding on this: when we worship, we can actually witnessed angels around us. All of us at our small groups were baffled by this recent phenomena. We could capture it on photos using many different cameras and at different locations where we have our worship. And I was using my PSR3000 believe it or not. I used many upbeat styles and ballads. So, the angels and the Man upstairs seem to enjoy our worship very much. And lo and behold, we heard this phenomena happening at other churches as reported on Charisma, a popular Christian magazine.
