What is a non-traditional scale employed by composers in the late 19th and 20th centuries consisting of 6 pitches spaced a whole tone apart?

• A. Whole tone scale
• B. Pentatonic scale
• C. Hexatonic scale
• D. Chromatic scale

Answer: (A)

The whole tone scale is a non-traditional scale that consists of six pitches, each spaced a whole tone apart, creating a unique and ambiguous sound that differs from traditional scales, which often include half-step intervals. This scale was frequently used by composers in the late 19th and 20th centuries to evoke an ethereal or dreamlike quality in their music. The absence of semitones in the whole tone scale also means it lacks a tonal center, contributing to its distinctive character and its effectiveness in expressionism and modernism within the musical context of that era. Other scales presented in the options serve different purposes in music. The pentatonic scale is made up of five pitches and is often found in folk music, while the chromatic scale includes all twelve pitches in an octave, making it a comprehensive yet more traditional scale for any harmonic or melodic structure. The hexatonic scale, while it consists of six pitches, does not specifically adhere to the whole tone structure of being spaced solely by whole tones, which is essential in the context of this question.
