WHAT IS A CHORD?
The simple answer: Three or more notes played simultaneously is a chord. (Two notes played together is an "interval" -- an interval being the distance between two different notes. This is also referred to as a "harmony. ") Depending on the intervals between the three or more notes, a chord can sound beautiful or muddy and dissonant. The organization of notes in the example at left -- a triad chord -- produces a pleasant, harmonious sound. Triads are made up of three notes and are the most basic and common chords in most music.
In this triad, the lowest note is the "root. " The root (also called the "tonic") is the most important note in the chord, because it anchors the sound harmonically by determining its "key" and forms the basis for how we hear the other notes of the chord. The second note of this chord is four semitones higher than the first, and the third is three semitones higher than the second. Keeping our root note fixed and changing these notes by a semitone up or down (sharp or flat), we can create four different chords.

Keep in mind that we can also change the "voicing" of a chord -- for example, change the order of the notes (called "inversions"), or play the same notes in different octaves -- without changing the basic nature of the chord itself.
Inversion examples for the key of C G E C C G E E C G
Beautiful sounding harmonies can be built in this manner. The use of intervals and chords is one of the most important elements in music. A wide variety of emotions and feelings can be created depending on the types of chords used and the order in which they are arranged.

WRITING CHORD NAMES
Knowing how to read and write chord names is an easy yet invaluable skill. Chords are often written in a kind of shorthand that makes them instantly recognizable (and gives you the freedom to play them with the voicing or inversion that you prefer). Once you understand the basic principles of harmony and chords, it's very simple to use this shorthand to write out the chords of a song. If you need to specify sharp or flat, indicate that to the right of the root. Examples for the key of C are shown below.
Major chord Minor chord Augmented chord Diminished chord
C
Cm
Caug
Cdim
For simple major chords, the type is omitted.
One important point: Chords are made up of notes "stacked" on top of each other, and the stacked notes are indicated in the chord name of the chord type as a number -- the number being the distance of the note from the root. (See the keyboard diagram below. ) For example, the minor 6th chord includes the 6th note of the scale, the major 7th chord has the 7th note of the scale, etc.
