What is the harmonic minor scale pattern?

The harmonic minor scale is characterized by its unique pattern of whole and half steps, which is designed to create a distinctive sound, particularly in classical and modal music. The correct pattern for the harmonic minor scale alternates whole steps and half steps in a specific way.

In the case of the harmonic minor scale, the pattern follows: whole step (W), half step (H), whole step (W), whole step (W), half step (H), whole and a half step (W+H), and finally a half step (H). This combination creates a raised seventh degree compared to the natural minor scale, which enhances the tension and resolution in harmonic progressions.

This scale is especially useful in creating leading tones in the dominant seventh chords, which is vital in classical music compositions. The specific intervals result in a sound that is both exotic and emotionally charged, making it a preferred choice for composers looking to evoke strong feelings or dramatic effects in their music.

The other patterns provided do not correctly represent the harmonic minor scale. They either lack the necessary raised seventh or differ in step sequences, which would alter the scale's distinct tonal qualities.
