Doctor Who: EVERY Fifteenth Doctor Episode Ranked Worst To Best

6. The Devil's Chord

Those repeated notes that Maestro plays on the piano signalled, more directly than Space Babies before it, that the audience was entering a new era of Doctor Who. Walls were broken, music was banished, and gods chuckled once more.

The Devil's Chord lives and dies on the strength of its performers. Jinkx Monsoon soars as the god of music, hell bent on destroying all life in the universe. The Doctor and Ruby stumble into them, casually trying to listen to The Beatles recording in Abby Road (bad news for them. Maestro took the rights to that music away).

The episode contains a number of fourth wall-breaking moments, including jokes about diagetic music, cameos from composers and dancers, and an uproarious sing-along at the end. 

It's certainly one of the more stylised episodes in the latest run of the show, and contains a few plot points that remain unresolved, but The Devil's Chord offered intrigue, pathos, Susan Twist making some damn fine tea, and a peek behind the curtain at the era that birthed the franchise. 

It's also just a lot of bloody fun.
