The Wobbly Piano on Pink Floyd's 'See Emily Play': Tape Loops, Vari-Speed, and Syd Barrett's Hand

The seasick, wobbling piano that opens “See Emily Play” wasn’t an accident—it was a deliberate studio trick driven by Syd Barrett’s obsession with warping sound. Engineer Norman Smith recalled that Barrett wanted the piano to sound “like it was underwater.” The solution: record a single piano chord onto a tape loop, then play it back while manually varying the speed (vari-speed) of the tape machine. The pitch rose and fell as the playback speed shifted, creating that wobbly, dizzying effect.

Barrett didn’t just request the effect—he likely helped shape it. He had been experimenting with tape loops at home and in live settings, feeding sounds through his Binson Echorec and overloading his Selmer amp. For “See Emily Play,” he also slowed down the entire master tape at one point
