How are the three types of minor scales (melodic, harmonic, and natural) different?

There are three types of minor scales in music theory. Each of these scales produces a different sound, but all are anchored by the minor third scale degree, which gives the minor tonality its recognizable sound.

The natural minor scale is the most common minor scale, and the default when a musician refers to “a minor scale” or “minor.” The natural minor scale pattern features the same exact notes as the Aeolian mode in modal music.

The harmonic minor scale is derivative of the minor scale where the seventh scale degree is raised by a half step.

The melodic minor scale is a minor scale with raised sixth and seventh scale degrees, but only when ascending. A descending melodic minor scale is identical to a natural minor scale.

pitch- the definition of pitch is as follows:

"the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone."
