C♯ AND D♭ NATURAL MINOR SCALE

C♯ Natural Minor Scale

The C-sharp natural minor scale follows the key signature of its relative major: E major. In natural minor scales, there are no additional accidentals.

The relative major key of C-sharp minor is E major. Therefore, C-sharp minor has four sharps (F♯, C♯, G♯, D♯).

D♭ Natural Minor Scale

The D-flat natural minor scale follows the key signature of its relative major: F♭ major. In natural minor scales, there are no additional accidentals.

The relative major key of D-flat minor is F-flat major. Therefore, D-flat minor has six flats and one double-flat: E♭, A♭, D♭, G♭, C♭, F♭, B♭♭.

TIP: To find the relative major key, count up three half-steps from the minor key’s root note.

C♯ AND D♭ HARMONIC MINOR SCALE

C♯ Harmonic Minor Scale

Harmonic minor scales follow the key signature of the relative major key and raise the seventh note of the scale by one half-step.

The relative major key of C-sharp minor is E major and the seventh note of C-sharp minor is B. Therefore, C-sharp harmonic minor has four sharps (F♯, C♯, G♯, D♯) but B is raised to B♯.

D♭ Harmonic Minor Scale

Harmonic minor scales follow the key signature of the relative major key and raise the seventh note of the scale by one half-step.

The relative major key of D-flat minor is F-flat major and the seventh note of D-flat minor is C♭. Therefore, D-flat harmonic minor has six flats (E♭, A♭, D♭, G♭, C♭, F♭), one double flat (B♭♭), and the seventh note (C♭) is raised up a half-step to C.

C♯ AND D♭ MELODIC MINOR SCALE

C♯ Melodic Minor Scale – Ascending

In melodic minor scales, we raise the sixth and seventh notes up one half-step when ascending and lower them back down when descending. Melodic minor scales follow the key signature of the scale’s relative major.

The relative major key of C-sharp minor is E major. Therefore, C-sharp minor has four sharps (F♯, C♯, G♯, D♯) and A and B are the sixth and seventh notes. We raise A and B to A♯ and B♯ when ascending the melodic minor scale, and we lower them back to A and B when descending.

C♯ Melodic Minor Scale – Descending

D♭ Melodic Minor Scale – Ascending

In melodic minor scales, we raise the sixth and seventh notes up one half-step when ascending and lower them back down when descending. Melodic minor scales follow the key signature of the scale’s relative major.

The relative major key of D-flat minor is F-flat major. Therefore, D-flat minor has six flats (E♭, A♭, D♭, G♭, C♭, F♭), one double flat (B♭♭) and B♭♭ and C♭ are the sixth and seventh notes. We raise B♭♭ and C♭ to B♭ and C when ascending the melodic minor scale, and we lower them back down to B♭♭ and C♭ when descending.
