What is the term for a six-note scale consisting entirely of whole steps?

The term for a six-note scale consisting entirely of whole steps is known as the Whole Tone Scale. This scale is constructed by taking consecutive whole steps, resulting in a unique sound that is distinct from the more commonly used scales like the Major and Minor scales.

The Whole Tone Scale does not contain any half steps, which contributes to its dreamy and ambiguous character, making it quite different from traditional tonal music. It can be represented in two variations (each containing the same pitches, just starting from different notes) but always adheres to the structure of whole steps only.

In contrast, the Minor Scale and Major Scale incorporate both whole and half steps, making them more familiar and commonly used in Western music. The Chromatic Scale consists of all twelve pitches within an octave, moving by half steps, which also distinguishes it from the Whole Tone Scale.
