Whole Tone Scale – Definition
A whole tone scale is a six-note scale made up entirely of whole-tone intervals. Because every step is the same size, the scale has a unique symmetrical structure and an ambiguous tonal quality.
What is the Whole Tone Scale?
Each note in the whole tone scale is separated from the next by a whole tone (whole step). Since the octave contains twelve semitones, only six different notes fit into the scale before it repeats.
Unlike major and minor scales, the whole tone scale contains no leading tone and no strong sense of tonal center. This gives it a floating, dreamlike, and often mysterious sound. Because of its symmetrical construction, there are only two distinct whole tone scales.
How is the Whole Tone Scale used in piano playing?
Pianists often use the whole tone scale for improvisation, especially over dominant seventh chords with altered extensions such as a raised fifth. The scale is common in jazz, impressionist music, film scores, and modern harmony.
Its distinctive sound makes it an excellent choice for creating suspense, mystery, or a sense of weightlessness. Learning the whole tone scale also helps pianists understand symmetrical scales and expanded harmonic possibilities.
