The Whole Tone Scale is a musical scale that consists entirely of whole steps, meaning each note is a whole tone away from the next. This creates a dreamy, ethereal sound that is often used in impressionistic music. Unlike the more common major and minor scales, the whole tone scale has no half steps, which gives it a unique, ambiguous quality. Composed of six notes, the whole tone scale can start on any pitch, such as C or D. Famous composers like Claude Debussy and Maurice Ravel have utilized this scale to evoke feelings of mystery and fluidity in their compositions.
