It is a scale made up exclusively of whole steps, as distinct from the standard western diatonic scale that is built upon the structure whole-whole-half-whole-whole-whole-half. For example, starting at E flat, the notes of a whole tone scale would be E flat, F, G, A, B, D flat.
A scale made up of only semitones is called a "chromatic scale." In this scale, each successive note is a half step apart, covering all twelve pitches within an octave. The chromatic scale is often used in music to create tension and complexity, allowing for a wide range of melodic and harmonic possibilities.

2 Half steps
A pentatonic scale is made up of 5 notes, and can be hemitonic (containing half steps) or anhemitonic (not containing half steps).
The major scale made up of five whole steps is the C major scale. In musical terms, it consists of seven notes and includes two half steps, which occur between the third and fourth notes and between the seventh and eighth notes of the scale. Therefore, in total, the C major scale has five whole steps and two half steps.
