I was Protestant before and guitars, keyboards, and drums are commonplace at many churches because they are not usually playing hymns, but, rather contemporary christian music or praise and worship songs.
That being said, we have a guitar and percussion at our monthly Frassati Holy Hours, and I enjoy that. I also enjoy the cantors and piano during Mass. My brother really dislikes the singing, but he also lacks rhythm!
Anyway, I am learning guitar so that I can lead worship at our parish’s new youth group and so I can travel to other churches, Catholic or not, and lead worship. But that’s me and I know it’s not for everyone. Oh, and BTW, our parish is staffed by Dominican Friars from the St. Joseph Province.
