Chords are usually made up of combinations of major and minor third intervals. All of the chords you have learned up to this point have been triads (3 note chords). There are four basic types of triads: major, minor, augmented and diminished. The following diagrams demonstrate each of these triads are along with the formula for each one.
This example demonstrates the four basic types of triads shown on the previous pages.
All types of chords can be played in different positions on the piano in various inversions. This example demonstrates how the four basic triad types could be used in a more musical manner. The right hand plays voicings which are close together on the piano, while the left hand outlines each chord as an arpeggio starting from the root.
