In the song BrokEn by Coldplay there are lyrics sung by the lead singer that are repeated by a background choir;
Lord, when I'm broken (when I'm broken) I'm in need (I'm in need) I feel that ocean (feel that ocean) Swallowing me (swallowing me)
It reminds me of Gospel music. Is there a name for this kind of back-and-forth in music? Or are there genres in which this occurs often?
