The chromatic scale is totally different from all other scales that exist in music. It includes all the piano notes that are located on the piano keyboard. So it would be correct to say that this scale is made up of twelve semitones.
According to the book “Music an Appreciation (4th Edition)” by Roger Kamien, the word chromatic comes from the Greek word ‘chroma’. The Greek word ‘chroma’ means color.
Major, minor, blues and pentatonic scales all have a particular structure according to the intervals used to form them. However, chromatic scales are constructed by playing all the notes that exist within one octave. This means that you will be playing half-tones or half-steps from the root note to its relative octave. For example – The notes that make up the G chromatic are as follows;
If you should play all the notes in this scale in the same order on your piano or keyboard, you will notice that you are playing semitone movements.
Just a quick reminder! B to C and E to F are semitone
movements whether you go in forward and backward motion. These are the
only set of white keys that form semitones on the piano.

Chromatic scales have no key signature and so they are dependent on major and minor key signatures when inserted in the melody of a musical piece. One of the easiest way to learn to play this scale on your piano is by playing it in the key of C. In this case, the scale will be called C chromatic.

It is important that you pay close attention to the fingers used when
playing this type of scale with both hands on the piano. When practicing
scales with a chromatic structure on your piano, try not to focus only
on one octave, but try playing it in at least two. However, playing it
in four octaves is a great way to exercise your fingers which is good
for piano players who love to do solos and play classical music. I am
sure you will see the benefits in the future.
