How can you tell if a chord is a major or minor or diminished or aug etc...
Well for one thing ,you will notice the SOUND of the chord, each one of those chords you mentioned, have a distint sound associated with them.
MAJOR = 1_3_5 = CEG
MINOR = 1_b3_5 = CEbC
DIMINISHED = 1_b3_b5 = CEbGb
AUGMENTED = 1_3_#5 = CEAb
MAJOR 7th = 1_3_5_7 = CEGB
DOMINANT 7th = 1_3_5_b7 = CEGBb
MINOR 7th = 1_b3_5_b7 = CEbGBb
DIMINISHED 7th = 1_b3_b5_bb7 = CEbGbA
AUGMENTED 7th = 1_3_b6_b7 = CEGAbBb
Listen to them, do the inversions for them, memorize the numbering for them. Hope this helped... :wink:
