As a follow-up to Tommy, Pete Townsend embarked on another opera-type project called Lifehouse. It never really materialized but some of the songs written for it appeared in 1971 on Who's Next. Behind Blue Eyes has some different parts that use a wide variety of techniques. It opens with arpeggiated picking over chords in the key of E minor, followed with some basic strumming through the chorus, then adds a short sample of Pete's signature double-time strum, before changing modes and rocking out a bit. This has been one of our most requested lessons for quite a while.
