What is a whole tone scale?

A whole tone scale is a musical scale that is made up entirely of whole tone intervals. This means that each note in the scale is separated by a whole step, or two half steps.

The whole tone scale is symmetrical, meaning that it repeats the same interval pattern throughout the scale. This gives the scale a unique and ethereal sound, often described as dreamy or otherworldly.

Because of its symmetrical nature, the whole tone scale does not have a distinct tonal center or key, making it sound ambiguous and lacking a sense of resolution. This makes it a popular choice for composers looking to create a sense of tension or mystery in their music.

The whole tone scale is commonly used in jazz, impressionist, and contemporary classical music, where its distinct sound can add texture and color to a composition. It is also used in film and television scores to create a sense of unease or suspense.

Some famous examples of pieces that use the whole tone scale include Debussy's "Syrinx" and "Voiles," as well as the theme music for "The Simpsons" television show.
