Where can I find a formula chord chart for minor keys?

All the ones I see in Google images are for major keys. How come?

  • I found this http://musictheory.pugetsound.edu/mt21c/DiatonicChordsInMinor.html It’s not a formula chart but it spells them all out in Am which is helpful. – John Belzaguy Feb 21 '21 at 16:51
  • Where can i find X questions are off-topic, but the core question seems to be about minor key harmony so I've closed this question as a dupe the goes over the basics of minor key harmony. – Dom Feb 21 '21 at 20:06
  • Lookong for chordcharts formulas: https://www.google.com/search?q=piano+chord+formula+chart+pdf&rlz=1C9BKJA_enCH812CH813&oq=formula+chord+chart&aqs=chrome.2.69i57j0i22i30l4j69i60.15150j0j7&hl=de&sourceid=chrome-mobile&ie=UTF-8#imgrc=_ https://www.google.com/search?q=piano+chord+formula+chart+pdf&rlz=1C9BKJA_enCH812CH813&oq=formula+chord+chart&aqs=chrome.2.69i57j0i22i30l4j69i60.15150j0j7&hl=de&sourceid=chrome-mobile&ie=UTF-8#imgrc=pkn_Te9TyWR-MM major and minor – Albrecht Hügli Feb 21 '21 at 20:13
  • @AlbrechtHügli Well those are all major. Hence the question. – Randy Zeitman Feb 21 '21 at 20:53
  • No, there are always 2 columns, major and minor. – Albrecht Hügli Feb 21 '21 at 21:27
  • @AlbrechtHügli Yes, they are the minor chord formulas relative to the major key. The formula for a minor chord in a natural minor key would be 1-3-5. – Randy Zeitman Feb 22 '21 at 04:12

It's because there's more than one minor scale.

In the natural minor, the chords are the same as the major scale, but they fall on different scale tones:

i=minor ii=diminished III=Major iv=minor v=minor VI=Major VII=Major

Using the harmonic minor scale, any chord with the 7th scale degree changes: III=augmented V=Major vii=diminished

And if you use the melodic minor* any chord with the 6th scale degree can change: ii=minor IV=Major vi=diminished

*often defined as the "melodic minor ascending", but in practice composers may use a raised sixth when the melody is descending

    For clarity it might be good to point out that the changes in harmony for the melodic minor also include the changes mentioned for the harmonic minor... – John Belzaguy Feb 21 '21 at 16:47
