Whole Tone – Definition

A whole tone is an interval equal to two semitones. On the piano, it is usually the distance between two keys with one key in between. In American English, a whole tone is also commonly called a whole step.

What is a Whole Tone?

A whole tone is one of the fundamental intervals in Western music. It consists of two semitones and plays a central role in the construction of major and minor scales.

For example, the distance from C to D is a whole tone because C♯ lies between them. Likewise, F to G and A♭ to B♭ are whole tones. Two whole tones together form a major third.

How is a Whole Tone used in piano playing?

Understanding whole tones is essential for learning scales, chords, and intervals. Major scales follow a specific pattern of whole tones and semitones, making it important for pianists to recognize these distances instinctively.

As pianists practice scales and technical exercises, they develop a natural awareness of whole-tone intervals, helping them navigate the keyboard accurately in every key.
