The Beatles were extremely influential in their time.
“Tomorrow Never Knows,” the final track on their 1966 album Revolver, is a great example of that influence. Primarily composed by John Lennon, it showcased the band’s growing interest in psychedelia, Eastern philosophy, and inventive recording techniques. Drawing on Timothy Leary’s adaptation of The Tibetan Book of the Dead, the song carries a meditative, otherworldly mood that felt completely new back then.
From a production standpoint, “Tomorrow Never Knows” was a big step forward. Producer George Martin and engineer Geoff Emerick experimented with tape loops, reversed guitar parts, and fed Lennon’s voice through a Leslie speaker, creating an eerie, swirling vocal effect. Instead of following the usual chord patterns of pop music, the track relies on a single chord and Ringo Starr’s steady, hypnotic drum beat—another choice that set it apart from the era’s standard sound.
This spirit of experimentation didn’t stop with Revolver. Soon after, the band recorded “Strawberry Fields Forever,” which also broke with traditional song structures through layered arrangements, unconventional techniques, and introspective lyrics. Taken together, these tracks paved the way for the psychedelic era that followed, showing how The Beatles consistently pushed music forward and made a lasting impact on popular culture.
Music was much different back then, and the changes we see today can, in part, be traced back to The Beatles and their willingness to rewrite the rules.
