Not By Might by Robin Mark is a great one!
We have a book of just chord progressions, 3 or 4 chords per page. At alter call we will play a progression and then repeat whatever the pastor's message was on...this last week the message was about blind Bartimaeus, and how he cried out to Jesus "Jesus have mercy on me!" So we repeated this chorus - the Rhema word - that God had given us thru the Word, and go from there. Then I think we added" I was blind but now I see"
Worship is very powerful and fresh this way...kinda another dimension .. just ask your other team members to repeat the word that God gives you and stay on that thought for 5-10 times thru...When you stay on the same chords it is easy for others to follow and sing along too.
I also watch the prayer room at IHOP - and have been to a few local Houses of Prayer in our area...this has helped me immensely in being open to the Spirit and letting God lead...
I'm kind of curious about this thread - how many of you are using repetitive choruses already? How long do they last? What portion of your worship service is devoted to this? We don't actually use any at the moment, so I'm curious how this works.
