minor: R - b3 - 5
augmented: R - 3 - #5
diminished: R - b3 - b5
R being the root... and the 3 and 5 correspond to the 3rd and 5th notes of the respective notes in that key...
Then if you want to further that... you can add the 7th.
Major 7: R-3-5-7
Dominant 7: R-3-5-b7
Minor/Major 7: R-b3-5-7
Minor 7: R-b3-5-b7
Half Diminished 7: R-b3-b5-b7
Diminished 7: R-b3-b5-6 (bb7)
Augmented 7: R-3-5#-7
Pretty easy and good stuff!!
