Dominant Chord in minor key?

Question

In a minor key, e.g. E minor, if you take the dominant triad, it contains the leading note. Is the leading note of the **natural minor** or the major for the dominant triad? So for E minor dominant triad is it (B,**D#**,F#) or (B,**D**,F#)?

Answer 1

Most commonly

It would be (B D F#) for the natural minor.

It would be (B D# F#) for the harmonic minor.

It would be (B D# F#) for the melodic minor.

Answer 2

Hi, That's what separates Natural minor scale from Harmonic minor scale. In the key of E minor, if the 5th chord of the scale is B minor (B D F#) this is a E natural minor scale. If the 5th degree is B (B D# F#) or B dominant 7th (B D# F# A) this is more likely Harmonic minor or it could be melodic minor. To understand which we would have to look at the chord progression more in depth. Would this be helpful?
