Question

What type of scale uses the 12 tones of the octave scale?

1) Major scale
2) Minor scale
3) Chromatic scale
4) Pentatonic scale

Answer 1

The Chromatic scale is the one that uses all 12 tones of the octave scale, with each tone being a half-step apart from the next.

Step-by-step explanation:

The type of scale that uses the 12 tones of the octave scale is the Chromatic scale. Unlike the Major scale which has a sequence of whole and half steps creating a specific pattern of 7 notes, and the Minor scale which also consists of 7 notes but with a different pattern of whole and half steps, the Chromatic scale includes all 12 tones within an octave. Each tone is a half-step apart from the next, creating a scale that includes every note possible within a single octave. The Pentatonic scale consists of only 5 notes, so it cannot be the one that includes all 12 tones of the octave.
