Wendy Carlos is known for her innovative work in electronic music and her contributions to film scores, including her work on "Beauty and the Beast." While she did not invent a new musical scale specifically for "Beauty and the Beast," she is recognized for her use of various scales and tuning systems in her compositions.

In her broader work, Carlos has explored microtonality and alternative tuning systems, which can include scales that deviate from the traditional Western 12-tone equal temperament. One notable scale she has worked with is the "just intonation" scale, which is based on the natural harmonic series and can create different emotional and tonal qualities in music.
