Hidden message

This article is about coded text. For text the same color as the background, see Hidden text.

A hidden message is information that is not immediately noticeable, and that must be discovered or uncovered and interpreted before it can be known. Hidden messages include backwards audio messages, hidden visual messages and symbolic or cryptic codes such as a crossword or cipher. Although there are many legitimate examples of hidden messages created with techniques such as backmasking and steganography, many so-called hidden messages are merely fanciful imaginings or apophany.

Description

The information in hidden messages is not immediately noticeable; it must be discovered or uncovered, and interpreted before it can be known. Hidden messages include backwards audio messages, hidden visual messages, and symbolic or cryptic codes such as a crossword or cipher. There are many legitimate examples of hidden messages, though many are imaginings.

Backward audio messages

A backward message in an audio recording is only fully apparent when the recording is played reversed. Some backward messages are produced by deliberate backmasking, while others are simply phonetic reversals resulting from random combinations of words. Backward messages in various mediums, including music, video games, music videos, movies, and television shows.

Backmasking

Main article: Backmasking

Backmasking is a recording technique in which a message is recorded backwards onto a track that is meant to be played forwards. It was popularized by The Beatles, who used backward vocals and instrumentation on their 1966 album Revolver. The technique has also been used to censor words or phrases for "clean" releases of songs.

Backmasking has been a controversial topic in the United States since the 1980s, when allegations of its use for Satanic purposes were made against prominent rock musicians, leading to record-burnings and proposed anti-backmasking legislation by state and federal governments. In debate are both the existence of backmasked Satanic messages and their purported ability to subliminally affect listeners.

Examples of backmasking

Phonetic reversal

Main article: Phonetic reversal

Certain phrases produce a different phrase when their phonemes are reversed—a process known as phonetic reversal. For example, "kiss" backwards sounds like "sick", and so the title of Yoko Ono's "Kiss Kiss Kiss" sounds like "Sick Sick Sick" or "Six Six Six" backwards. The Paul is dead phenomenon was started in part because a phonetic reversal of "Number nine" (the words were constantly repeated in Revolution 9) was interpreted as "Turn me on, dead man".

According to proponents of reverse speech, phonetic reversal occurs unknowingly during normal speech.

Visual messages

Hidden messages can be created in visual mediums with techniques such as hidden text and steganography.
