Last class was sort of a continuation of last week's class. We talked about the diatonic chords in a minor key. You remember the diatonic chords in a major key, right?
I ii iii IV V vi vii°
The diatonic chords in a minor key are similar, with one exception. First, think of the minor chords as the relative minors to the major chords. If we begin on scale degree 6 (vi) and turn it into our new 1 (i), we can write our minor chords as follows:
i ii° III iv v VI VII
Does that make sense? The relative minor of a major key (take C major, for example) is a 3rd below the tonic (so the relative minor of C major is A minor). So our tonic chord (the one chord) for A minor is the same as the vi chord in C major.
Here's the exception I was talking about. Remember minor scales -- natural, harmonic, melodic? I talked about how the harmonic scale was the most used minor scale. This is because the 7th scale degree is raised a half step. This raised 7th scale degree creates a nice lead-in to the 1, and is used more than the regular, diatonic natural 7. Anyway, if we raise the 7th scale scale degree in our minor chords, we change the chords that use the 7th. This means the v chord, whose middle tone is the 7th degree, becomes major (V) and the VII chord, whose root is the 7th degree, becomes diminished (vii°). We will leave the III chord alone for right now, even though its top note is the 7th degree. So with those two changes, we now have:

If you don't quite understand yet, don't worry. We'll review much of this next semester as we get into more composition. For now, just remember that the V chord is major whether you are in a minor key or a major key (and also that the vii° chord is diminished).
By the way, we do have class this coming Monday (December 1). Thanks again for your faithfulness. God bless!
