Answer:

D minor

Explanation:

D is the relative minor of F major, so had you used these clues to figure out the “major” side of things (which would have been “F” had I asked for the major key), then the minor key would be a piece of cake.

Why? Because relative major and minor keys share the same key signature, scale tones, and chords.

So if you take the chords associated with the F major scale and simply “shift” them over so that “D” starts and ends the series of chords, you’re good to go! It’s that simple.

1st tone – F major (F A C)
2nd tone – G minor (G Bb D)
3rd tone – A minor (A C E)
4th tone – Bb major (Bb D F)
5th tone – C major (C E G)
6th tone – D minor (D F A)
7th tone – E diminished (E G Bb)
1st tone – F major (F A C)
2nd tone – G minor (G Bb D)
3rd tone – A minor (A C E)
4th tone – Bb major (Bb D F)
5th tone – C major (C E G)
6th tone – D minor (D F A)
7th tone – E diminished (E G Bb)

See the chords I’ve bold? Those are the same exact chords but instead of thinking of them in terms of “F major” (that is, with “F” as the starting and ending tone), I’ve emphasized them so that you can see how it works when you’re looking at the relative minor of the key. Same notes, same chords — DIFFERENT reference points… starting and ending notes. That’s it.

So when someone asks you to play in a minor key, if you know how to play in the relative major key, you should be fine!

(Oh, and just in case… you find the relative minor of any major key by going to the 6th tone. “D” is the 6th tone of “F major.” If you’re in a minor key and want to find the relative major, just go to the third tone of the minor scale. “F” is the 3rd tone of “D minor.” So that’s how all this works).

Here are all the relative major/minor relationships:

Relative Major / Relative Minor

C major / A minor
Db major / Bb minor
D major / B minor
Eb major / C minor
E major / C# minor
F major / D minor
F# major / D# minor
G major / E minor
Ab major / F minor
A major / F# minor
Bb major / G minor
B major / G# minor

I hope this helps.

Until next time —
