Hey! Quick question. Trying to wrap my head around this.

In Harmonic Minor Scale, Why didn’t changing the V chord to dominant (making it a G#) impact the rest of the chords? If the chords are all built off the scale, shouldn’t the C Major chord now have G# in it? Or any chord with a G?

Thanks!

It does, and this makes it a C augmented chord.
A good challenge to yourself would be to write the A natural minor and the A harmonic minor scales, to then build their triads and name them by stacking in thirds then once done compare and contrast.

Ah, that’s great idea, thanks! I’ll try that out.

In the video at 2:48, Justin gives an example where he would go Am to C to Dm to E7 back to Am. I think that part is tripping me up a bit. Would those be the chords in the key of Am? Im assuming not, based on what we just clarified. Or was he just giving a random example to show the perfect cadence?

Thanks!

Yes, totally.
The dominant E7 resolution to tonic Am is the reason for the harmonic minor scale.
Often songs will be discussed as being in the minor key (meaning natural minor) and shifting to harmonic minor temporarily when that dominant 7 chord comes along. Progressions do not tend to be written solely in the key of harmonic minor using its diatonic chords. It is a composer’s tool to use only when needed, in small doses.
