Chord
formulas for augmented,
diminished, sus2, and sus4 chords
Once you understand the concept of the chord formulas
that you learned so far, you can start to put together an understanding
of how the other 3 note chords are constructed. Just remember
that the function numbers ( 3,
3, 5,  5,
etc.) are just how the notes in the chord relate to the major
scale that has the same root as the chord.
Here are the formulas for the remaining 3 note chords.
augmented
chord formula = 1 3 5
diminished chord formula = 1 3
5
sus2 chord formula = 1 2 5
sus4 chord formula =

Part
2 of this lesson will cover how to spell any 3 note chord.
Part
3
will cover how to further apply the theory learned in the previous
parts to the neck of the bass. You will learn how to alter basic
chord and arpeggio shapes that you already know to form other
types of chords. coming soon
