Jazz Piano Chords
It's helpful to know that the 12 major chords are built from their corresponding major scales, and the 12 minor chords are built from their corresponding minor scales.
Many of the commonly used jazz chords are built by adding a note to a major or minor chord, or by making a slight change to a major or minor chord.
Using the C major scale shown above, the 1st note of the scale is a C, the 3rd note of the scale is an E, and the 5th note of the scale is a G.
Now I could list the eight notes of the Cm scale to build the Cm chord, but there's an easier way. Once you know the 12 major chords, all you have to do is lower the middle note of the chord, or the 3rd, and you've created a minor chord.
Remember what I said earlier... many of the commonly used jazz chords are built by adding a note to a major or minor chord, or by making a slight change to a major or minor chord.
In this case, the slight change was made by lowering of the 3rd of the C major chord, (the E), to make it C minor. (The E becomes an E flat). It really is that easy, and it's exactly the same for the remaining 11 major chords.
