The 2-5-1 movement is used right across music but heavily in Soul, Gospel and Jazz music.
R&B has adopted this progression and usage and has gone to town with it. We used to hear it a lot in the 90s but now its back in full effect. You’ll hear it in 1 out of 10 R&B with Trap style drum songs. From Chris Breezy to Kehlani and everyone in-between.
