Write something in harmonic minor.
Now, to be more specific, I might call it "write something that uses harmonic minor." If you've watched my Music Theory Monday Series, you're familiar with the harmonic minor scale and the resulting chords that come with. If you haven't watched that series yet, I recommend at least watching the first three episodes or so.
For example I'll use the key of B Minor
Natural B Minor uses these notes:
B C# D E F# G A B
and has these chords:
i = Bm
ii° = C#°
III = D
iv = Em
v = F#m
VI = G
VII = A
harmonic minor scales use a sharp 7th note like this:
B C# D E F# G A# B
And the most significant impact this has on our chords-in-a-key is that the v chord (F#m) becomes a major V chord, but more specifically, it becomes a dominant 7th chord (F#7) which resolves back to i (Bm) beautifully.
You are welcome to participate in whatever capacity you like! Wether you write a fully complete song with guitar, lyrics, bass, drums or you just record an 8 second rough sketch to your phone, all submissions are equally welcome. The only requirement is that you write it AFTER reading this post.
I'm going to be pretty flexible on the other "rules" here because harmonic and melodic minor get thrown together in the same situations often, but to put it simply:
if you write a chord progression starting with natural minor chords, then just turn the V chord dominant, you've essentially written a harmonic minor chord progression.
Melodically, if you write a melody over that progression and make sure the 7th note of the scale is sharp when then V chord is happening, you've basically written a harmonic minor melody over your progression!
