The notes of the D harmonic minor scale are D, E, F, G, A, B flat, C#, D.
d, e, f, g, a, a# + c
D E F G A Bflat Csharp D
The notes of the A harmonic minor scale are A, B, C, D, E, F, G#, A.Natural minor: A, B, C, D, E, F, G, AHarmonic minor: A, B, C, D, E, F, G#, AMelodic minor: A, B, C, D, E, F#, G#, A, G, F, E, D, C, B, A
The notes in a G harmonic minor scale are: G A B flat C D E Flat F# G
In B harmonic Minor, you lower the third and sixth scale degree from the B major scale. So your notes will be B, C#, D, E, F#, G, A#, B There are three forms of minor: Harmonic, Melodic, and Natural.
The chord of Em contains the notes E, G, and B. The scale of E minor contains the notes E, F♯, G, A, B, C, and D.
D E F G A B flat C D
D E F G A Bb C# D
D E F G A Bflat Csharp D
A, b, c, d, e, f, g, a. (Natural minor)
The notes of the A harmonic minor scale are A, B, C, D, E, F, G#, A.Natural minor: A, B, C, D, E, F, G, AHarmonic minor: A, B, C, D, E, F, G#, AMelodic minor: A, B, C, D, E, F#, G#, A, G, F, E, D, C, B, A
The notes in a G harmonic minor scale are: G A B flat C D E Flat F# G
In B harmonic Minor, you lower the third and sixth scale degree from the B major scale. So your notes will be B, C#, D, E, F#, G, A#, B There are three forms of minor: Harmonic, Melodic, and Natural.
The notes for E minor pentatonic are E, G, A, B, and D. All naturals!
The D-minor scale is D, E, F, G, A, B flat, C. The F major scale is F, G, A, B flat, C, D, E. So there is really no difference, other than the order of the notes.
The chord of Em contains the notes E, G, and B. The scale of E minor contains the notes E, F♯, G, A, B, C, and D.
C, D, and E are the first three notes of the C major scale.
There is not three notes in any scale or key, if you are asking about the accidentals, there is one flat (Bb) in the key signature plus an additional C sharp for the harmonic minor scale.
