What's the history of using a worship set in church, rather than interspersed songs

I have heard the arguments for and against an extended time of worship at the start of a church service. My question, though, is more historical. **Where did this approach to sung worship originate; as opposed to songs or hymns interspersed throughout the service?** For example, every charistmatic/pentecostal church I've been to, in more than one country, has the same basic structure (half an hour or so of sung worship, then the sermon, then maybe another song or two at the end). There must be a common root for that somewhere. Did some worship leaders get together once and discuss it? Or did some megachurch do it, and then it was copied from there? Or did churches start to copy rock concerts and then it became the norm? Or something else? **Where did this specific idea of having a "worship set" at the start of the service come from?**
