We in the Messianic Movement are outside the mainstream of contemporary worship music, but with the recent popularity of Paul Wilbur and his daugher in law Sharon (daughter of Messianic music pioneer Joel Chernoff) we are becoming more mainstream.
I have noticed the trend away from "oompah oompah boom-chucka" songs and even occasionally major key tunes finding their way into the mix.. Batya Segal (of Yemenite decent) has done some interesting songs and arranged some other old stand-bys into a no-chord middle eastern sound. The style is more driven from Israel.
It's good to see (or hear) music that hearkens to older traditions -- if we are all mixing and blending the colors of the various styles and ethnicities, it can become like mixing all the bright clay or the paint colors and coming up with plain old brown.
Just listened to Hinue la Yanom -- oh, is that beautiful!
Some of the older Messianic music was based on Klezmer, an eastern European Jewish style; but it required a clarinet or a sax or a violinist with SERIOUS chops. (think the clarinet cadenza that starts off Rhapsody in Blue)
Recently the NY orthodox community have come up with a style (or range of styles) that are interesting and I would LIKE to see incorporated into Messianic music. (there is resistance from our Israeli brothers who decry it as the music of their oppressors)
A couple of examples:
Avraham Fried Hine Ma Tov = "Behold how good" from Psalm 133.1
Mendy Wald Chazak = "Be strong" from Joshua 1
That sounds like a lot of fun if you ask me. I love to see different cultural music traditions make their way into worship music. And it would certainly be healthy to see some of this stuff get fused with popular Christian worship music.
And this brings up an interesting point. Every culture will find their most natural voice for worship and it tends to come from their own music. And music is all relative and heavily influenced by the past, so no one can claim complete originality. I think this is why we see a lack of any kind of Biblical commands for a given style or type of music.
I mean, I have yet to find a Bible verse that insists that all worship music must be 19th century hymnology even though so many missionaries have tried to force this on indigenous populations. And Bill Gothard has tried to argue this from scripture in a rather convoluted way.
I think we should encourage people to express things in a way they find enjoyable. (That's a loaded statement for sure.)
I am currently involved in planting a church in a neighborhood with approximately 120 different people-groups represented.
When people ask me what our music is going to be like, I happily shrug my shoulders and say, "I don't know. It depends on which people God allows us to lead to Himself."
