A Summary of Triads

The terms major, minor, diminished, and augmented refer to the quality of the chords. In this case, the term quality does not refer to something that is good or bad, but it is simply a description that allows us to distinguish one chord from another.
There are several different systems of symbols used for identifying triads. This website will use the following symbols for each chord:

Major = Maj
Minor = min
Diminished = dim
Augmented = aug

These abbreviations are commonly used in printed music, and allow us to avoid writing the complete name of the quality of each chord.

Listen to each triad in the Flash example below. (If you are unable to hear them, visit www.adobe.com for the latest Flash update.)
