Chromatic Scale in Music Theory

What is a scale made up entirely of half steps?

A. the whole scale
B. harmonic minor scale
C. chromatic scale
D. major scale

Answer: C. Chromatic Scale

Chromatic scale is that formed by 12 notes with semitone intervals between them.

The chromatic scale is a scale made up of all half steps. It consists of all 12 notes in an octave, each separated by a half step. These 12 notes include all the natural notes (A, B, C, D, E, F, G) as well as the sharp and flat notes in between each natural note. The chromatic scale is a fundamental concept in music theory and forms the basis for understanding harmony, melody, and composition.

Explanation:

Although the chromatic scale is not usually used to its full extent in musical contexts, small chromatic passages are common. They are used by composers from various periods such as baroque composers like Bach, romantics like Chopin, and moderns like Schoenberg who developed dodecaphonism. In popular music, chromaticism is often used in improvisation and the use of approaching or passing notes.
