For those who may not have heard of this classic urban legend of music, Jan Dirk Blom provides this explanation in his Dictionary of Hallucinations
The term Dark Side of the Rainbow
denotes a peculiar pattern of thematic similarities that can be discerned while one is watching The Wizard of Oz
while simultaneously listening to The Dark Side of the Moon
. With the aid of this somewhat unusual procedure, over a hundred instances of perceived interplay have been reported by fans.
It is not known who ﬁrst established this pattern of thematic similarities, but from 1994 onwards it was widely discussed on internet sites such as the Usenet message board alt.music.pink-ﬂoyd and in the popular media.
As the Pink Floyd band members (save Roger Waters) have always denied deliberate attempts to synchronize their album with the movie, the Dark Side of the Rainbow
is commonly designated as a cognitive illusion and attributed to a process called apophenia
, i.e. an excess of perceptual or heuristic sensitivity leading to the discernment of patterns or connections in random or meaningless data.
If you're curious to experience this phenomenon for yourself, someone has helpfully posted the entirety of the Wizard of Oz
on YouTube, synced to Dark Side of the Moon
Though this raises the biggest problem with the theory: Dark Side of the Moon
is about 43 minutes long, while the Wizard of Oz
is over an hour long. In the video below, this is solved by simply looping the album.
Some of the synchronicities to look for:
Look for a triangle hanging in the tree, that looks kinda like the triangle on the cover of Dark Side of the Moon.
Bells start playing just as Margaret Hamilton (the Wicked Witch) rides onscreen, ringing the bell of her bicycle.
The song 'Money' starts playing when Dorothy first lays eyes on the Yellow Brick Road, which was often seen as a metaphor for bricks of gold, or money.
When the Wicked Witch, dressed in black, appears out of a cloud of smoke, the lyrics say "black, black, black..."
As Dorothy is first talking to the Scarecrow, and (in the movie) he begins singing "If I only had a brain," the song "Brain Damage" starts to play.
When Dorothy meets the Tin Man and bangs on his chest to listen for his heart, the album ends and fades to a heartbeat sound.
