The octatonic scale alternates between whole and half steps, and is therefore a combination of the principles behind the chromatic scale and the wholetone scale. In the examples below, the scale begins with a half step, but beginning with a whole step is also possible. Whichever interval comes first, there are only three collections of pitches that can be used to create octatonic scales. Like the wholetone scale, any further transpositions will only duplicate an existing collection.
