I go by the old "1 3 5" and "1 b3 b5" and such for chord construction out of the modes, is that the same one you use?
wrong or right, I use these formula's for chord construction. i don't use the triad approach, but i am aware of it.
for a major key i use;
-ii Sub Dominant
-IV Sub Dominant
now insert any major mode scale. the uppercase roman numerals denote major chord and lower case denotes minor chord. the vii(7th) is a dominant, but it is a minor7b5 or diminished.
and for minor modes i use this.
- i Tonic
- ii Sub Dominant
- III Tonic
- iv Sub Dominant
- v Dominant
- VI Tonic
- VII Dominant
with the minor key you will want to start your chords from the Natural minor scale keeping the minor and major tonalities. notice the upper and lower case has changed from the major, but not the tonic, sub-dominant's or dominant's
so in the key of Am
- tonic chord can move towards a dominant directly.
- the sub-dominant can move either back to a tonic chord or to a dominant.
- dominant moves almost forcefully to a tonic chord
you can now try and put in the major modes for the major key and the minor modes for the minor key and come up with tons of chord progression's.
i hope someone wiser can help fill in any hole's i may have. which i know there are. this is just how i was taught.
