In 1998, Cher released 'Believe,' a song that would not only revitalize her career but also change the sound of popular music forever. At the age of 52, Cher became the oldest woman to have a number-one hit on the Billboard Hot 100. The song is most famous for its pioneering use of Auto-Tune as a creative vocal effect, rather than a corrective tool. This 'robotic' vocal sound was so revolutionary at the time that her producers initially lied to the press, claiming they had used a vocoder to protect their secret production technique. The effect became known globally as the 'Cher Effect.' 'Believe' was a massive international hit, topping the charts in over 23 countries and becoming the best-selling single by a solo female artist in the UK. It remains a landmark in electronic dance music and a testament to Cher's ability to reinvent herself for new generations.
