chromatic scale
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.
