How The Beatles Recorded Tomorrow Never Knows

The Beatles' recording of Tomorrow Never Knows, released on the 1966 album Revolver, marked one of the most radical moments in the history of popular music.

The song introduced recording techniques that would influence countless musicians and producers in the decades that followed.

Inspiration Behind the Song

The lyrics of Tomorrow Never Knows were inspired by The Tibetan Book of the Dead, which John Lennon encountered through Timothy Leary's adaptation of the text.

The song's concept reflected Lennon's interest in Eastern philosophy and psychedelic experience.

Tape Loop Experiments

One of the most innovative aspects of the recording involved the use of tape loops.

Members of the band created short segments of recorded sound that were played simultaneously on multiple tape machines.

These loops produced unusual effects including:

distorted guitar sounds
reversed orchestral fragments
seagull-like audio textures

Vocal Processing

John Lennon wanted his voice to sound as if it were "coming from the top of a mountain".

Producer George Martin and engineer Geoff Emerick achieved this by routing Lennon's vocal through a Leslie speaker, a device normally used with Hammond organs.

A New Approach to Recording

The techniques used on Tomorrow Never Knows demonstrated how the recording studio itself could become a creative instrument.

The song helped redefine the possibilities of rock music and influenced later developments in electronic music, psychedelia and experimental production.
