The harmonic minor scale is a variation of the natural minor scale, characterized by a raised seventh note. This alteration creates a distinctive sound that is often described as exotic or dramatic. For example, in the A harmonic minor scale, the notes are A, B, C, D, E, F, and G#. The raised seventh (G#) leads to a stronger resolution to the tonic note (A), making it popular in various musical genres. This scale is frequently used in classical music, jazz, and metal genres, as it enhances harmonic progressions and adds tension. Composers and musicians often employ the harmonic minor scale to create emotional depth and complexity in their compositions.
