Uses of Auto-Tune
At the January 2001 International Music Products Association show in Anaheim, California, Antares performed a demonstration of Auto-Tune in which they fed the output of a Theremin into Auto-Tune. The effect was described as "like putting adjustable frets into thin air".
The harmonization is intended to increase the musical quality of a vocal track without revealing the singing as processed. Still, with extreme parameter values, the Auto-Tune has also become popular as a distinctively electronic voice effect, similar to a vocoder. The most familiar example of Auto-Tune is the Cher effect, named for Cher, whose producers originated the effect in her 1998 hit song "Believe". Cher's "Believe" was in fact the first commercial song which used Auto-Tune as a deliberate, creative sound effect instead of the equipment's main purpose. When first interviewed about this, the sound engineers claimed they had used a vocoder in an attempt to preserve this as a trade secret.
The Singer T-Pain has also used a different version of the effect in his music and that of other artists, to great success.
Use of Auto-Tune is not confined to Western pop music -- the product comes with Arabic scales, and has become very common in Arabic music. In 2007 Saudi singer Muhammed Abduh told journalists that today is the era of 'Auto Tune', where singers rely on machines to fix their voices.
According to the Boston Herald, "Country stars Reba McEntire, Faith Hill and Tim McGraw have all confessed to using Auto-Tune in performance, claiming it is a safety net that guarantees ticket buyers a spot-on show."
