Let’s learn how to build a diminished chord. To build a diminished chord you combine the root, flat third and flat fifth of the major scale. Here’s an easy way to form a diminished chord: You can start with a major chord and lower the 3rd and 5th notes of the chord by a half step or semitone. For instance, in the chord C diminished, lower E to E flat and lower G to G flat. A diminished chord is written dim or o. Example C diminished is written Cdim or Co.

How to build an augmented chord

Let’s learn how to build an augmented chord. To build an augmented chord you combine the root, third and sharp fifth of the major scale. Here’s a quick and easy way to form an augmented chord: simply hold a major chord then raise the fifth note of the scale by a half step. For instance take the chord C and simply raise the note G by half a step to G#. The notes of C augmented would therefore be C E and G#. An augmented chord is written aug or +. For example D augmented is written. Daug or D+.
