Hey Everyone,
Part of the song goes like this:
The whole choir sings, "Hallelu (pause), Hallelu (pause), Hallelu (pause), Hallelu (pause)
And then the sopranos sing "Hallelu" then the Altos sing "Hallelu" and then the tenors, bases and baritones sing Hallelu and do it one by one in succession like Hallelu, Hallelu, Hallelu, Hallelu, Hallelu, etc, Then they go on to sing Hallelujah, Hallelujah, Hallelujah, Hallelujah, Hallelujah.
I know the base (left hand of the piano) goes something like this
Ab,C,Db,D,Eb,F,G,Ab
I tried my best to explain this, I hope someone can help!
