LOL!!! But with regards to chords, they can be catagorized in several differnt ways. Most guitar players start out with basic "root postion" or "1st inversion chords in which the root is the lowest voice. Chrods are made up of at least three notes (root, third, and fitth) and are classifed as major or minor depending on if it contains a natural or a flat third (there is also the diminshed chord which contains both the flat 3rd and the flat 5th). As a result, the chordal patter for any given major scale is:
I. Major (includes Maj. 7th and all extentions)
II. Minor (includes Min. 7th and all extentions)
III. Minor (includes Min. 7th and all extentions)
IV. Major (includes Maj. 7th and all extentions)
V. Major (includes Dom. 7th and all extentions - Dom. 7th chords have a flattened 7th)
VI. Minor (includes Min. 7th and all extentions)
VII. Diminished (includes Half-Diminished 7th)
The three major chords (I - IV - V) are refered to as the "primary chords" and essentailly lay the foundation for most songs. The minor and diminished chords can be used to dress things up a bit and add some color. Then too, there are many songs that are built around the minor chords. And then there are other inversions that place the root in higher voicings with other tones in the bass. Inversions may not be as important to learn early on especially if you're in a band situaton where the bass player or keyboardist can define the chordal structures. They can be very useful for solo performances as they add a sense of movement to the bass.
